Take a look at the Comparable[1] module. It's a much cleaner, simpler
way to accomplish what you're doing.

Kinda reminds me of when I spoke at length with Stan Freberg -- he
didn't so much sound as though he was a Beatles fan as he was proud
that he himself had been famous enough to get the Fabs to pose for a
photo with his kids!

On a tangent, I just recently found out that an old U-matic tape that
I thought was blanked actually still has about 2/3rds of a 30 minute
Jerry Pam interview still on it. It's from the late '70s, though, and
doesn't seem to have any Beatles content...

I was wondering if he might be a bit on the curmudgeonly side vis a
vis the Beatles, he was more of a 'beatnick' type back in those days,
I seem to recall him being associated with Lenny Bruce and some other
Greenwich Villiage troublemakers.
