In contrast to the two previous albums, on which the band tends more towards classical blues, the album 'Then Play On' showed a wider range of styles. It is the last album of the group with Peter Green before he left the band and the first with Danny Kirwan, who was to stay until 1972. Oh Well' was the successful single that, although not on the album, would contribute to the continued popularity of Fleetwood Mac. The band took the success with them on a short tour of Finland, during which this gig was recorded in Helsinki. The LP comes as 180 Gr. and Dark Green Colored!
