While the information is only about the first recording to hit the top 40, Joel Washburn's Pop Memories, 1890-954 is a great source.

SMoke Gets In Your Eyes was recoreded in 1934 by:

   Paul Whiteman who had the number One hit
   Leo Reisman
   Emil Coleman
   Ruth Etting

The next time that the song charted in the top 40 was in 1941m by Artie Shaw.

As for It's All In The Game, the first time that it hit the charts was in 1951 by Tommy Edwards.

Zoom was recorded by the Cadillacs in 1956. And you are genius, Vilan. When the Marcels recorded Blue Moon, they'd just been listening to Zoom, by the Cadillacs and the opening bass line is an exact copy of the one for Zoom. When they auditioned for recording, they sang Zoom, just to showcase their singing and when they were asked to do Blue Moon, they just started out with the classic bass introduction. They got the song in just two takes. Just as well. They only had 8 minutes left of studio time.

Those were the days.

If you love Doo Wop, or just vocal groups, I'd highly recommend American Singing Groups by Jay Warner. It covers the whole spectrum, from the Ink Spots and Modernaires to Manhattan Transfer, and has fascinating stories to tell.
