Fred Rose acted as A&R man for Sterling [Hank's first 8 recordings] then when Hank got his MGM contract Fred was still the A&R man. Fred used studio musicians on Hanks recordings until Jan. 1950. After that he used Hank's road band. I would have to know what songs you listened to so I could tell you the side men. Hank never used twin fiddles, the fiddler just played double and/or triple stops. Starting Jan. 1950, Hank's road band played on most of the recordings until the end of Hank's life. The fiddler was Jerry Rivers, died 1996, and the steel man was Don Helms, still living and playing steel for Hank's daughter, Jett Williams. Don still uses the same 1948 double 8 Gibson Console Grand model that he played on the Hank recordings. If you will e-mail me direct with song names, I'll tell you when they were recorded and who the musicians are. MGM overdubbed some of Hank's recordings and added strings, electric bass, drums, piano and tried to erase as much of the original music as they could. I don't like those records and won't talk about them.
