"Supper's Ready" was performed live in its entirety for the first time at
Brunel University in Uxbridge, on 10 November 1972, several months into the Foxtrot Tour. The tour lasted until mid-1973, by which time it became a centrepiece of the live show and a showcase for Gabriel's on-stage storytelling and costumes to act out the various parts. Genesis performed the song during their subsequent tour promoting the next album,
Selling England by the Pound (1973), until April 1974. Following Gabriel's departure in the following year, Genesis performed "Supper's Ready" live in 1976, 1977, and in 1982. The final two sections were performed twice in 1978 and in 1986 as part of a medley of the group's old material. A shortened version of the song was rehearsed for
The Last Domino? Tour, but ultimately not performed. Gabriel's costumes debuted at the band's headlining concert at London's
Rainbow Theatre in February 1973. For "The Guaranteed Eternal Sanctuary Man", Gabriel would don a
crown of thorns headpiece. For "Willow Farm", he wore a flower mask designed by Guy Chapman, inspired by the character Little Weed from the children's television programme
Flower Pot Men. Banks said Gabriel would adopt his "
music hall persona" for this section, "and he became even more the centre of attention." For "Apocalypse in 9/8", Gabriel wore a
Magog outfit consisting of a black cloak with a triangular box headgear with lights for a pair of eyes. An image of Gabriel in this costume was printed on the front cover of the live album,
Genesis Live (1973). His performance would climax for "As Sure as Eggs is Eggs" with the firing of a flash charge of magnesium powder and Gabriel would discard his Magog costume to reveal himself in shining white apparel and luminous makeup, holding a fluorescent light tube as the rest of the stage was in darkness. On some shows during the
Selling England tour, Gabriel was lifted above the stage on a wire during this section. During one of these shows, the wires started twisting and he was nearly strangled. Gabriel would introduce the song with a story. A recording from October 1973 with his story was released on the 1998 box set
Genesis Archive 1967–75. He said: "Old Michael went past the pet shop, which was never open, into the park, which was never closed. And the park was full of a very smooth, clean, green grass. So he took off all his clothes and began rubbing his flesh into the wet, clean, green grass. He accompanied himself with a little tune – it went like this." Gabriel would briefly perform
scat singing to Collins's drum accompaniment. Gabriel continues: "Beneath the ground, the dirty brown writhing things called 'worms' interpreted the pitter-patter from above as rainfall. Rainfall in worm world means two things: mating and bath time. Both of these experiences were thoroughly enjoyable to the worm colony. Within seconds, the entire surface of the park was a mass of dirty, brown, soggy, writhing forms. He was still pleased, Old Michael, and he began whistling a tune this time to accompany himself." Gabriel then briefly whistles the beginning of the hymn
Jerusalem. He concludes: "Jerusalem Boogie to us, perhaps. But to the birds it meant that supper was ready." ==Analysis==
