The hit version of the song was recorded by Perry Como on December 28, 1959. It was released by RCA Victor as a 45rpm single with catalog number 47-7670 and as a stereophonic single with catalog number 61-7670. The flip side was "I Know What God Is". The record reached #22 on the Billboard charts in March 1960.[3] The 2 sides were co-charted in Canada, reaching number 16.[4]
The same recording, with the same B-side, was released by RCA Victor in the United Kingdom (catalog number 1170) where, oddly, it sold even better than in the U.S., reaching #3 on the UK Singles Chart.[3]
