Lib Dem Glee Club
Astoundingly, a real thing that actually exists. Since time immemorial the Liberal Party has ended its conference by getting plastered and having a sing-along of political filksongs, and after the great merger with the SDP the tradition continued, with the addition of a few songs griping about the merger itself. Other popular themes include the Irish Land Acts, how crap the policies of the other parties are, and how crap the Liberal Democrats are at winning elections.
Simon Hughes, Paddy Ashdown, and Tim Farron are regulars. In recent years Nick Clegg has stopped coming, but that's okay. The Glee Club brought their own copy.
Lib Dem Glee Club: you never know who will turn up.
Every year a new songbook is produced with new songs added and the most irrelevant/unfunny taken out. Below is a collection of some of the best/most important songs sun at Glee Club, taken from the 2010 song book.
