 Bootleg editions of Barrett 's live and solo material exist . For years the " off air " recordings of the BBC sessions with Barrett 's Pink Floyd circulated , until an engineer who had taken a tape of the early Pink Floyd gave it back to the BBC — which played it during a tribute to John Peel on their website . During this tribute , the first Peel programme ( Top Gear ) was aired in its entirety . This show featured the 1967 live versions of " Flaming " , " Set the Controls for the Heart of the Sun " , and a brief 90 @-@ second snippet of the instrumental " Reaction in G " . In 2012 , engineer Andy Jackson said he had found " a huge box of assorted tapes " , in Mason 's possession , containing versions of R & B songs that ( the Barrett @-@ era ) Pink Floyd played in their early years .
