Good song, but they didn't mention Sir Terry's achievement: since George RR Martin began GoT in 1996, Sir Terry published 38 books (well, I'm including the one coming out in October, since it's in final processing). That's even more than Shakespeare's 35 plays. I guess Shakespeare fits the meter better.
He's also editing about 49 anthologies and writing 74 comic books as well as blogging about American football etc.
This man has brought procrastination to an art form
Annoying though his slow work is, I can actually sympathise, being a writer myself. And he's a far better writer than me. He should take his time where it is needed.
