One thing i've always wondered about the Sam Fox stuff, is how far in years it goes? Never found any mid - late 70's stuff. Was always very early 70's and earlier. Did it crap out after early 70's or is later stuff just mega rare?
The library actually started out publishing folios music for silent films, as well as popular music and marches. According to entries in
Business Screen Magazine, it went into the recorded music business in 1930, although the physical releases I've seen are likely mid-to-late 1960s, the run ending in I presume the early 70s. They also had a subsidiary in England, the Synchro Library of Recorded Music, those were released in the late 50s (1957-59). I suspect a lot of the material on this label was acquired, as you have material from British (definitely from Synchro), French (likely from the French Synchro-Disc label), Dutch (from the Sonorama label) and even Mexican composers in addition to the Americans like Joe Sherman and William Goldstein.
Love this label, too, and there's so much great stuff on it [Syd Dale's tracks in particular are brilliant, apparently recorded with the same musicians in Cologne who recorded a lot of the early KPM stuff]. Kinda overlooked when you compare it to, say, Walter Murphy's tracks on Valentino, Capitol, or the Tanner stuff, sadly.
If you're curious, some of my favorite tracks on the label and its branches overseas would be "Route Nationale" by Roger Roger [Synchro FM (pretty sure that stands for "Fox Music") 236), "Forever Frantic" by Robert Mersey [retitled "Dot and Dash" by the folks at Carlin Production Music], "Cool Bossa Nova" by Malcolm Lockyer [SF 1018] and "Sand Dance" by Syd Dale [SF 1015].
