Which Fleetwood Mac single was the band's only release on Immediate Records?

“Man of the World” was Fleetwood Mac's only single released on Immediate Records.

Peter Green wrote the song, and Fleetwood Mac recorded it in January 1969 during the band's early blues-rock period. The single was released in the United Kingdom on 4 April 1969, with “Somebody's Gonna Get Their Head Kicked in Tonite” on the B-side under the pseudonym Earl Vince and the Valiants.

The release followed the lapse of Fleetwood Mac's recording arrangement with Blue Horizon. The band's manager negotiated a new deal with Immediate Records, but the label soon collapsed, leaving “Man of the World” as the group's sole Immediate single. It reached No. 2 on the UK Singles Chart and spent 14 weeks on the listing.

The song is often mixed up with “Oh Well,” “Albatross” or “Need Your Love So Bad,” all notable early Fleetwood Mac singles issued in the same broad period. “Man of the World” is also important because it was the final Fleetwood Mac recording produced by Mike Vernon, whose work shaped the band's formative sound.
