"Oh Well" is a song first recorded by the rock band Fleetwood Mac in 1969, composed by vocalist and lead guitarist Peter Green.
"Oh Well" first appeared as a Fleetwood Mac single in various countries in 1969 and subsequently appeared on revised versions of that year's Then Play On album and the band's Greatest Hits album in 1971.
The song was later featured on the 1992 boxed set 25 Years - The Chain, on the 2002 compilation album The Best of Peter Green's Fleetwood Mac, and on the 2018 compilation 50 Years - Don't Stop.
"Oh Well" was composed in two parts, with "Part 1" as a fast electric blues song with vocals (lasting 2:19), and "Part 2" as an entirely different instrumental piece with a classical influence (lasting 5:39).
The original 1969 single features the first minute of "Part 2" as a fade-out coda to the A-side and then "Part 2" begins again on the B-side. Later releases varied in length.
During concerts, only the first part was played, and live versions of the song have been released on a handful of Fleetwood Mac live albums throughout their career such as Live and Live at the BBC, as well on the B-sides of singles. After Green's departure from Fleetwood Mac, the song was sung by various other members, including Bob Welch, Dave Walker, Lindsey Buckingham, Billy Burnette, and Mike Campbell.
