60's and early 70's. Dino Valenti died in I think 1994 from a growth in his brain that he apparently had for most of his life before it killed him.
He had one of the most unique voices in the music business. Songs included "Fresh Air" and "What About Me".
His sister set up the most remarkable web site as a tribute to him. It is the nicest web site I have seen for any musician. It is well worth a look. His mother and father were Carny performers and Dino's biography is very fascinating.

Neat site. I did recognize a few of the songs.
