Throughout April, the band took stock of their work. Waters blocked "Vegetable Man" and "Scream Thy Last Scream" from the album, but they retained "Jugband Blues" and "Set the Controls for the Heart of the Sun", on which Barrett played. Without enough material to fill an album, the band started putting together music that became the title track. Mason and Waters planned it out as if it were an architectural design, including peaks and troughs. Smith did not approve, telling them they had to stick to three-minute songs. On 25 June, the band recorded another session for the BBC show "Top Gear", including two tracks from the album: the session featured two tracks from Saucerful: "Let There Be More Light" and an abridged version of the title track, "The Massed Gadgets of Hercules".
