For what it's worth, the Erin Merle version of Reel Around The Fountain and Eduardo Luedy's The Headmaster Ritual are perennial favourites. I believe we had a poll some time ago and Erin Merle won. Also I'm quite fond of Vision's 'Stop Me'. And I'm also fond of the version of The Loop I did in my front room.
