The Union Chapel Concert is a live album by Guy Evans and Peter Hammill, recorded in the Union Chapel in London, 3 November 1996, and released as a double CD in March 1997. The album is noteworthy because it is the first time the four ex-members of Van der Graaf Generator, Hammill, Evans, Hugh Banton and David Jackson, played together in front of a paying audience since the band had broken up in 1978. The subtitle on the front of the album reads: "featuring a one song, one-off reformation of Van der Graaf Generator." David Jackson and Hugh Banton were unannounced guests and played a Soundbeam-medley and a Samuel Barber Adagio for strings on the church organ respectively. All songs that evening were played in varying line-ups. Only "Lemmings" was played by Hammill, Evans, Banton and Jackson.
