Such Waters warhorses as "Forty Days and Forty Nights", "I'm Ready", "Baby, Please Don't Go", and "Got My Mojo Working" were recorded and later released on the album "Fathers and Sons". Waters commented, "We did a lot of the things over we did with Little Walter and Jimmy Rogers and Elgin [Evans] on drums [an early configuration of Waters's band] ... It's about as close as I've been [to that feel] since I first recorded it". To one reviewer, these recordings represent Paul Butterfield's best performances. The Butterfield Blues Band was invited to perform at the Woodstock Festival on August 18, 1969. The band performed seven songs, and although its performance did not appear in the film "Woodstock", one song, "Love March", was included on the album "", released in 1970. In 2009, Butterfield was included in the expanded "40th Anniversary Edition Woodstock" video, and an additional two songs appeared on the box set "". The album "Keep On Moving", with only Butterfield remaining from the original lineup, was released in 1969. It was produced by veteran R&B producer and songwriter Jerry Ragovoy, reportedly brought in by Elektra to turn out a "breakout commercial hit". The album was not embraced by critics or long-time fans; however, it reached number 102 in the "Billboard" album chart. A live double album by the Butterfield Blues Band, "Live", was recorded March 21–22, 1970, at The Troubadour, in West Hollywood, California. By this time, the band included a four-piece horn section in what has been described as a "big-band Chicago blues with a jazz base". "Live" provides perhaps the best showcase for this unique "blues-jazz-rock-R&B hybrid sound". After the release of another soul-influenced album, "Sometimes I Just Feel Like Smilin"' in 1971, the Paul Butterfield Blues Band disbanded. In 1972, a retrospective of their career, "Golden Butter: The Best of the Paul Butterfield Blues Band", was released by Elektra. After the breakup of the Butterfield Blues Band and no longer under contract with Elektra, Butterfield retreated to Woodstock, New York, where he eventually formed his next band, Paul Butterfield's Better Days, with drummer Chris Parker, guitarist Amos Garrett, singer Geoff Muldaur, pianist Ronnie Barron and bassist Billy Rich.
