Well 2 of them are known on a lesser scale and 1 to greater degree
The Mints where a band that featured Ken Copeland. They had a big hit with a song called 'Night Air' credited as 'The Mints' on one side and 'Pledge of Love' credited only as 'Ken Copeland' on the other side. They did start out Lin Records as shown in the notes, but Line was a bit of small regional (Texas) indie label Busy Body Rock. Copeland abandoned rock'n'roll to become a TV preacher
Johnie and Jack had some rockabilly sides on RCA in the early 50s and are pretty well known among collectors
The biggie though would have be Charlie Gracie who had a big hits in 1957 with Butterfly and Fabulous on the US Cameo label.
For the most part I would tend to say that these tracks are strictly for anoraks though
