A very short interview with members of The Call at Greenbelt Festival 1990. The Greenbelt Festival is a festival of Christian rock bands held since 1974 in the UK. During the interview, The Call band members discuss working with Bono and T-Bone Burnett to create a demo for “Slow Dancing”, a song U2 would later record twice in the studio (once alone, and once with Willie Nelson). They also discuss Bono doing backing vocals for The Call song What’s Happened To You. Special thanks to Sue Fell for providing this interview. Recorded August 24th to August 27th, 1990.
