Topper is one of my favs (I am a massive Clash fan)...and yes, he did drive taxis, busked in the London tube at a low point after the Clash during his addiction, and what not. He is recovered now and looks fantastic (thank god)! He is doing a bit of drumming again. I wish he would do more. I would love to meet him.
Some recent tube of you links:
Seems a real humble chap, as well.
