Some segments of "TOTP" which have been wiped by the BBC do survive in some form owing to having been included in other programmes, either by the BBC itself or by foreign broadcasters. What was thought to be the only surviving footage of the Beatles on the programme, for instance, comes from its re-use in episode one of 1965 "Doctor Who" serial "The Chase". Additionally a number of recordings are believed to exist in private collections. However, in 2019, an 11-second clip of the group's only live appearance on "TOTP", from 16 June 1966, was unearthed – this was recorded by a viewer using an 8mm camera to film the live transmission on their television. Other individual but complete clips that have surfaced over recent years include The Hollies performing "Bus Stop", and The Jimi Hendrix Experience playing both "Purple Haze" and "The Wind Cries Mary".
