Full title = Tree (Today Is an Important Occasion)
With Les Miserables brass band. The performance of the Knee Plays (Music from the Civil Wars) was part of the concert for the ICA, shown on BBC2 in August 1988.
Top clip of the original line-up performing a song from the first album on some programme called "Mainstream". Repeated as part of the "Sounds of the Seventies" series, hence the daft bookending with Paul Darrow and Patrick Troughton.
Thanks to flinflanflon for the title.
