I would imagine that most of us have already heard this one, but for the benefit of those who haven't seen or heard an SAS Band show, here it is. This recording is very clear (soundboard I think). I hope you enjoy it. http://sasband.de/modules.php?name=Downloads&d_op=viewdownload&cid=2
P.S. To avoid any confusion, I'm just providing the link. The site is not mine, but I think it's quite good.
I'm as mad as HELL, and I'm not going to take this anymore!
