Personally, though, I pretty much sing along in the audience or write such things as The Online Song, Red Tape Come Again No More and Down Again!.
I don't get to go to as many performances as I used to, because I'm pretty busy with everything listed on my project page. But I keep this list of links as up-to-date as I can. Please email me if anything is out-of-date or you have anything to add.
And my own special interest, Sea Chanteys.
