Probably the wild clarinet flourishes - he rarely seemed to play woodwinds on songs that weren't his own. The other notable exceptions I can think of are Wide To Receive and It's Not Your Birthday Anymore - and Human Being as far as covers go.

I did say, 'There's a chance (if only a small one)'.
It is pretty unlikely especially if Alain didn't write any Bonfire songs as we've been led to believe.
Still, we'll find out soon enough!
