Comments: After winning the Harp Lager Talent Contest in March 1978 and receiving the chance to record a demo funded by CBS, U2 play a studio set on an unknown date in April 1978. The session lasted about half-an-hour and came to an end after Larry's father arrived. They play two cover songs at the end after running out of finished original material. "Concentration Cramp" and "Night Fright" are referred to on tape as "Concentration Camp" and "Night Flight" respectively.

Some short clips from this demo session were played by BP Fallon on his radio show in September 1982. Bootlegs containing recordings of Trevor and Jack in a Box are purported to be from this session, but the differing audio quality and live appearances of both lead us to believe they were from a session in February 1980.
