From Rolling Stone:
When Peter Gabriel launched his solo career in 1977, he was determined to make a name for himself outside of Genesis. His self-titled debut LP sounds nothing like the prog-rock Genesis created during his tenure in the band, and when he toured he padded out his setlist with “All Day and All of the Night” by the Kinks and Marvin Gaye’s “Ain’t That Peculiar” to avoid relying on the catalog of his old band.
Still, he didn’t want the Genesis fans to go home completely disappointed. On his 1977 tour he ended the show with “Back in New York City” from the 1974 Genesis album The Lamb Lies Down on Broadway, and the next year he closed out the night with the album’s title track. He even put on his old leather jacket from the Lamb stage show for the occasion.
