Phil Collins said that the Genesis song which most tested his vocal abilities was ‘Supper’s Ready’, the 23-minute progressive-rock suite from the band’s 1972 album *Foxtrot*. Although he could perform most of it, he found the ‘Willow Farm’ section beyond his range, illustrating the particular challenge of taking on material originally written and sung by Peter Gabriel.

Collins later became Genesis’s lead singer after Gabriel left, but the article contrasts his pop-oriented vocal style with the demanding, multi-part compositions of the group’s early era. ‘Supper’s Ready’ includes shifting rhythms, notably the ‘Apocalypse in 9/8’ section, while ‘Willow Farm’ requires intricate delivery and falsetto; Collins nevertheless described the rest of the piece as within his reach.
