You hear that alive and well in the double-time structure that I put in at the end, which on stage could last half an hour. It incorporated the freedom to go off on a tangent, to jam – the classic 'Do you jam, dude?' We learned that as players.

Mick Fleetwood ranked the song in his top 11 favourite Fleetwood Mac songs list. The second single fared much better, becoming the band's first song to chart on the Billboard Hot 100.

After the failure of "Rattlesnake Shake", "Oh Well" was chosen as the second single for the US market. While Davis thought "Rattlesnake Shake" would become a big hit, it failed to chart anywhere. Instead, Clifford Davis, who was Fleetwood Mac's manager at the time, selected " Rattlesnake Shake" to be released in the US. Īlthough " Oh Well" was a hit in the UK, it was not the group's first single released in America. Instead, Spencer released a solo album in 1970 with the members of Fleetwood Mac as his backing band. Green and Spencer had planned to record a concept album - “an orchestral-choral LP” - about the life of Jesus Christ, although the album never came to fruition. You just don’t hear about things like that.” Jeremy Spencer, the band's other guitarist, was retained even though he did not play on any of the album's original tracks. And Peter gave Danny all of that freedom. Music journalist Anthony Bozza remarked that Green “was a very generous band leader in every single way. Green, the de facto band leader at the time, delegated half of the songwriting to bandmate Danny Kirwan so he could sing more lead vocals. Green had recently introduced improvisation and jamming to the band's live performances and three of the tracks on the album including "Underway", "Searching for Madge", and "Fighting for Madge", which were compiled by Green from several hours of studio jam sessions. For the recording of Then Play On, editing and overdubbing techniques were used extensively for the first time.

It was the first of their original albums to feature Danny Kirwan (although he is also listed on two tracks on the earlier compilation The Pious Bird of Good Omen) and the last with Peter Green. Then Play On is the third studio album by the British blues rock band Fleetwood Mac, released on 19 September 1969.
