The service is not mentioned in the timetables or the LT allocation books.  The services operated again in 1962, and in 1963, the LT Central Buses Traffic Committee minutes state that the Kenwood Concerts Express Service, Sats 1 June to 20 July, was approved ‘as 1962’, with two buses 'forward traffic' from Edgware (EW) garage and five buses 'return traffic' (2 EW, 3 MH).  On 24 June, staff shortages and allocation problems are noted and the service was experiencing losses.  On 8 July, the service is still loss-making, having not operated 6 July due to bad weather but the staff were paid.  On the other hand, the minutes note that in fine weather, reliefs were required, especially at the break.  Whilst the minutes do not confirm that RFs were used on the service, the use of buses from MH and EW, the route following the 210, where it is believed that double-deckers were not acceptable to residents, together with the blind records (see below) all suggest that the service was RF-operated.

Stuart Perry confirms that the service did not operate from 1964 onwards, and that the RF blinds in use at MH in late 1963 did not include the service, although they did include the 251, which had moved away that spring.  This ties in with details from blind records provided by George Jasieniecki.  He records that, in 1960, a special RF blind was produced for Muswell Hill garage, with just one panel (as well as the obligatory 'blank', but no 'private').  The records show that 12 sets were produced, dated 10/6/60.  He assumes that the printed panel was blue, and the blank panel black, but the schedules didn't actually state this.  The wording on the panel was arranged in four lines, with 'Express' at the top. The second line read 'To & from Kenwood &', third line 'Golders Grn or Archway' and 'Single fare 6d' in the fourth line. All lettering in capital letters at that time.

Since it seems very unlikely (whatever the inside staff at the garage might have had to say about it) would not have been dressed (or at least intended to be dressed) front and back, this suggests a maximum of six buses, probably only five.  The fact that they were individual blinds, not added to the usual garage RF blind, suggests that there might have been an intention for some buses to be borrowed.  However, in summer 1960, MH put out 28 RFs on Sundays but only 19 on Saturdays – so why would they borrow?  The staff shortages and the use of buses from EW in 1963 (at least) seem to provide the answer.

Although sometimes loosely referred to as the '210 Express', and having used the same roads, the blind details indicate that the workings were not regarded as part of the 210.  We have no evidence that these blinds were actually used, although the lack of any Express panel on the MH garage RF blinds in 1963 suggests that they were.

Stuart Perry adds 'My experience of concerts at Kenwood [from 1964] was that you left Archway or Golders Green with a standing load, often with much grumbling from the queue, but I have no memory of getting help from any "extras".  I do know that if the weather was good a lot of passengers used the 271 to Highgate Village and enjoyed the walk from there.  If the weather was bad there were a lot less passengers anyway as of course the concerts were all open air and only the hardiest bothered to turn out.  I always got the impression that those who supported the concerts were choosy about the weather which was the major factor in how busy we were during the evening.'

It seems likely, given the losses recorded in 1963 and the well-known staff shortages at that time, that the service was withdrawn for some time.  George Jasieniecki comments 'Personally, I would not be surprised if it failed to appear as a London Transport operation for a while from 1964 onwards. There were extreme staff shortages around that time, and all resources available were concentrated on running normal scheduled routes with numbers. Private Hire, and special services for other events, such as Race Specials, football and so on, were contracted out and operated by commercial private coaches. Even the Round London Sightseeing Tour lost its Routemasters from New Cross, and was run by private coaches for several years. Bad for LT's image, of course, but they would have been criticised just as much if the resources on RLST were not redeployed.'

There seems to be no record of the period between 1964 and about 2004 (can anyone help?).   However, there is still a special service for Kenwood these days, but it operates separately to and from Golders Green and East Finchley stations.  This service has been operated by Sullivan Buses since about 2005, and Dean Sullivan provided the following details in early 2010:

'Yes we do run the Kenwood Shuttle and have done so for about five years.  The PVR is a minimum of 4 depending upon the concert. If it's busy, we put extra buses out. The bus is normally SLF double deck but Routemasters have regularly appeared. Other than the Routemasters, all SLF DD’s carry Kenwood displays.  The loadings do vary with the concert. One weekend when they had Simply Red and we were VERY well loaded. Golders Green creates the majority of passengers, roughly about double the loadings from East Finchley.

English Heritage [owners of Kenwood] run the free service for two reasons, firstly the 210 is unable to cope with the loadings at tip out, even though they now run double-deckers. There are also concerns expressed about the concerts by the local residents.  The concerts were cancelled in 2007 due to noise, and there are issues about the parking on event days.  The bus services are an attempt to reduce this problem.'
