From what I can gather these two labels were the budget arm of Adelaide’s EMS group. There appears to be around 30 releases mostly on Omega. Artists range from Patsy Biscoe to the Band of the 3rd Military District. Popular artists included Johnny Chester and the Everly Brothers.

As with many of these minor labels, they lasted from the very late 1970s to the very early 1980s. There were a large number of records of popular songs by uncredited session musicians.

Enough said.
