“Manchester England” is an extract from “Hair” which is sung before “Let the Sunshine In” and is equally famous. However, it requires a great choir work for being sung. You’ll need a soloist who would better be a tenor best accompanied by a pianist. The latter can improvise or play with a bassist and a drums player because the chords are mentioned. We also suggest you the score “Let the Sunshine In” (No. 87) also harmonized by Norbert Ott.
