Jack Straw
I look nothing like him!
You sure it wasn't the New Regent, also at the bottom of West St? Unless my memory's tricking me, that's where I saw Dillinger (in 1978, I think). The New Regent was a great venue, much smaller than the Top Rank but a nice, intimate vibe. I saw a few reggae acts there.
The Top Rank did have some reggae headliners - I saw Dennis Brown, Gregory Isaacs and Mikey Smith (just a few months before he was murdered) but there was a better atmosphere in the New Regent.
I'm pretty certain it was the Top Rank. Also there, I saw Toots & The Maytals, Heptones, Burning Spear, Selector, The Beat, and others I can't remember. I also saw Bob Marley at the Brighton Center, but that's another story.
