A recording of EVERYBODY WANTS TO GO TO HEAVEN by The Three Bars was announced in Billboard in October, 1950.

A review in Billboard of a live performance in New York by Tommy Dorsey's band, with vocalist Frances Irvin, says they performed it on November 9, 1950. (Dorsey also recorded it, but I haven't been able to establish the date.)

Billboard announced a recording by Les Brown's Band of Renown, with vocalist Butch Stone, on February, 16, 1952.

However, I suspect the song, or some version of it, or at least some song with that refrain, is older than that, but those are the oldest recordings or documented performances I can find.
