At 7.00 p.m., the VHF/FM (88 – 91 MHz) transmitters reverted to BBC Radio 2 only. The programme was listened to by millions and started with the sound of the Apollo mission's 'we have lift-off!' words. Sound effects, amongst many, included a racing car which indicated a record was rapidly moving up the top 20. Each chart position from 20 to number 1 had an individually numbered sung jingle provided by Pams Productions of Dallas, Texas which was played prior to each record. This group also created the jingle 'It's A Top Twenty Entry - Right!' which was used regularly on the programme. After the number 2 hit had finished playing, a further vocal run-down by Browne of numbers 20 down to 2 followed (with Browne's choice of background music) and then the number one record was announced and played which completed the programme. The chart was first broadcast (compiled by the British Market Research Bureau) on Johnnie Walker's programme the previous Tuesday (247 metres MW only) and played by Walker at that time. The music used for that rundown was Booker T. & the M.G.'s track, "Time is Tight". A further "sound effect" which may have been forgotten by many is the one used during the first two hours of the show to denote a record that was about to enter the top 20 which had the sound of a bubbling hot mixture with a vocal saying "This ones bubbling under" ! A sung jingle was also included in the first two hours for new releases which went.."Its a new one, a new one...repeated".
