Around 1970, Gibb played piano on George Harrison's song "Isn't It a Pity" as a part of his first triple solo album, "All Things Must Pass". In the recording studio he met Genesis' Phil Collins, Phil Spector, Ringo Starr, Billy Preston and Harrison. In 1971, he produced Lulu's 1971 song "Everybody Clap", which features Gibb on guitar, Leslie Harvey on guitar, former Manfred Mann and Cream member Jack Bruce on bass, and Led Zeppelin's John Bonham on drums. Bonham and his wife, Pat Philips became friends with Gibb and Lulu. Also in that year, he played bass on Billy Lawrie's 1973 song "Freedom". Future Wings and former Thunderclap Newman guitarist Jimmy McCulloch played guitar on that song, and McCulloch suggests that it was recorded at around the same time as Lulu's "Everybody Clap", with Stone the Crows' Maggie Bell providing backing vocals. On 17 January 1972, Gibb produced, with Billy Lawrie, "Baby Come on Home", released as a single also in that year. In April 1972, Gibb produced Jimmy Stevens' album "Don't Freak Me Out" (called "Paid My Dues" in US). The same year, Gibb produced "Drift Away", an album released by Bob Saker and Mike Berry; it includes a cover version of "On Time". In 1973, Gibb produced and play bass on Jimmy Stevens' unreleased numbers with musicians Alan Kendall, Jimmy McCulloch, Pete Willsher, Zoot Money and singer Paul Jones. In August 1973, Gibb participated on Andy Gibb's first recording session, performing two new songs.
