Did you know that in the beginning of the song Fat Old Sun you can hear the same bells that can be heard in the beginning of High Hopes? It is the sound of the Ely cathedral bells. Did you know that the song Coming Back To Life was used to wake up the astronauts of the Columbia space shuttle? There is a footage of the crew talking to the control center on the NASA website. Did you know that during one of the concerts Roger Waters told a drunk fan to come closer to the stage and then spat on him?
The recordings released on the album were recorded for the purposes of John Peels Top Gear Show which ran on BBC Radio 1. All of the songs were recorded on the 24th of February 1970. Songs such as Dominoes or Love Song were recorded during the session, too, but the tapes got lost from the BBC archive.
