The original Pink Floyd, obviously pre-Gilmour with Syd. The See Emily Play video was from the BBC performances that were almost lost to history. Pink Floyd performed the song three times on BBC TV's Top of the Pops. On each occasion, they mimed to the single, over which Barrett sang a live vocal. The BBC wiped the shows all of which were "live" transmissions. In late 2009 a badly damaged home video recording was recovered by the British Film Institute containing the first and third show the song was performed on, though only the first appearance was recoverable in part. The first performance was on the 6 July 1967 edition hosted by Alan Freeman. Parts of this performance have been recovered from the damaged video recording. Some reports are that it was a home recording, that someone pointed their camera at the TV and recorded it, and that the tape was found in an attic. If you look closely, you can see the TV scan lines. However it was found it is a priceless view into the band before their fame. Shine on you crazy diamond.
