Looking for a performer of vaudville-type act (removes "masks" while singing)

My friend and I are looking for this act (i.e., videos thereof). Here is my friend’s description:

there is one thing i can’t find on the internet
it was a guy i saw on Jerry Lewis’s telethon actually
Jerry would put people on there who would never otherwise be seen outside of hotels for old people type theatres. because that’s where jerry came from
and this guy had a great schitick
he would be singing a song, or talking. then move his hand up to his face like he was removing a mask and throwing the mask onto the ground, and when he did this he never actually removed a mask but just changed his facial expression. so it looked as if he actually had removed a mask. as it went one he went faster and faster. changing masks, moving back to old masks. totally hilarious, one of a kind thing

Thanks for any help you can offer!

Surely someone knows!

Nobody on this board save you is going to admit to watching a Jerry Lewis telethon.

Wasn’t that some godawful PBS pledge week-dwarfing cavalcade of craptacular dancing with the stars-level performers smeared over all three (and the only three) networks, completely ruining any chance of catching a decent batch of Saturday morning cartoons?

I hope someone helps the OP because at least someone found something good on it.

Could it possibly have been Art Metrano (or The Great Metrano)?
