Williams' Solid Gold label was active as early as in 1956, although Billboard announced the founding of Solid Gold in its March 24, 1958, issue. Many of the records which appeared on Solid Gold were maufactured by RCA, at least every 45 from 1956 to 1959. From that point on, the label used various pressing plants. Judging from the few Billboard reviews/ads and the obscurity of the artists, Solid Gold was only a small label out of Indiana. The adress was 359 Burgess Avenue, Indianapolis.
Nabor, one of Williams' other labels, was very similar. It was affliated with Solid Gold and was based on 243 South Summit Street in Indianapolis. Many of the releases were pressed by Rite, some also by King and RCA. Artists on Nabor included Tommy Lam (of "Speed Limit" rock-a-billy fame) and Charlie Stewart. The last known singles were released around 1972 by Nabor.
The last label Williams owned was Yolk, which was also headquartered in Summit Street, Indiana. It first appeared in 1960 releasing a gospel EP by Ron Frazer and several country/rockabilly singles, including Lloyd Harp's "Slow Boogie Rock" (Yolk 102). Nearly all Yolk records were pressed by Rite, one by RCA (Yolk 501 by Matt Huston) and the last known single by King (Yolk 130 by Andy & the Carbon Hillbillies) in 1964.
Both Nabor and Solid Gold labels were part of the Nabor Recording Company and it wouldn't surprise me if many of the releases were recorded in Jan Eden's studio in Indianapolis. Don't know a thing about Jerry Williams' later life. Solid Gold Records made one last appereance in 2000, when the label released a compilation of Aubrey Cagle's rockabilly songs.
Thanks to Bob for his addition about Yolk. If anyone of you has more info on Jerry Williams or his labels, feel free to contact me. Thanks Bob!
