This one is a bit of a head scratcher. Credited on the pre-Band Box label Columbine as Johnnie Dwyer with Billy Lee and the Rocky Mountain Playboys. As there tended to be several bands calling themselves the same thing, I have no clue whether these guys are affiliated with Hank Locklin's, Jimmy Snow's, Rocky Rauch's Rocky Mountain Playboys.
A 1949 issue of Desert Magazine notes:
December meeting of the San Fernando Valley Mineral and Gem society of Se- pulveda was a Christmas party and pro- gram including songs and recitations. John and Johnnie Anderson furnished music with their electric guitars; the Craig family acted out a skit portraying a night on a field trip; Johnnie Mitchell, Mary Newbold, Mr. Lil- jibald, and Master Johnnie Dwyer sang, and Master Hal Dwyer recited "What Are Rockhounds?"
Johnnie (Johnny) went on to record at least one single on the Dee Jay label, re-recording "Love Grown Cold," with The Pike County Players--again there apparently was more than one group calling themselves that (sigh).
That said, this is a sweet country ditty.
