{OK, if you guys don't have the 'Barenaked Ladies: Rock Spectacle'
album, you won't know it. It's about a minute after the last song
(which is If I had $1,000,000 by the way) and it is an improv. by them.
It's hilarious, so here are the lyrics}

It's Uncle Elwyn,
It's Uncle Elwyn.

My Uncle Elwyn is tall,
My Elwyn is small,
My Elwyn plays a mean
Basketball

He's about 45,
maybe 55, 60.
I'm not sure,
Once he mixed me

A drink, I was 'bout
5 years old
It was Kool-Aid, and bought,
I thought that was cold.

Cold meaning good
Cold's s'posed to be bad
I think that I
ought'a would

Change some things,
Change their meanings.
I've been here,
Iv'e been demeaning.

Once, twice,
Maybe three times
I asked my Uncle Elwyn,
He's a mime,
He said

It's Uncle Elwyn,
It's Uncle Elwyn,

That's E-L-W-Y-N
That's Elwyn, say it again.

E-L-W-Y-N
That's Elwyn, say it again.

E-L-W-Y-N
That's Elwyn, say it again.

E-L-W-Y-N
That's Elwyn

That's my uncle.
