In 1977, after Hugh Banton and David Jackson had left Van der Graaf Generator, Potter was asked to re-join. He plays on both The Quiet Zone/The Pleasure Dome (1977) and the double live-album Vital (1978). However, he was still uncomfortable with the dynamic of the band as he had been previously, stating "sometimes it felt like a cloud coming down – a very ominous feeling." He was particularly concerned at a gig in Annecy, France where he claimed someone was trying to perform an exorcism of the band's music while on stage, and had to be helped back to the dressing room, feeling very shaken.
