G'day Gadge
I feel you would make a brilliant eclectic music historian!
I kept shaking my head with disbelief at the 'Blue Rondo' link
Folks at home will know the brilliant Brubeck from Take 5 HERE.

As a teen, I had a pisstake album of the Beatles.

You have now educated me - a cover or tribute band
is not quite a pisstake band.

Gadge, I now realise ... I'm an amateur!

I'm too scared - now - to investigate 10CC and Steely Dan.
My parents might have said, "Jack, don't go there!".

Cheers
