Ok A while back I saw a old dr. seuss movie that was live action and made while he was still alive. It dealt with a bunch of kids at this music place and the bad guy had to get all of them to play on these pianos at once curious if anyone knows the name of it

That's an easy one :)
5000 Fingers For Doctor T

It totally bombed though.

Just a very small correction LD. It is the 5000 Fingers of Dr. T.

The 5,000 Fingers of Dr. T. (1953)

I loved Hans Conreid in it, used to give me nightmares.

Oh, yes that's right Ruby :)
Well.. I nearly got it right.
