There 
were two Top Dog labels. This one, based in Louisville, Kentucky in 1966 and 1967 had nine releases, all with 2300 series catalog numbers. It was owned by Ray Allen (Floyd Lewellyn) and Hardy Martin as were Boss, Bridges, Jam, Rondo and Tilt.
The Louisville Top Dog label had some good releases, like the Keyes “She’s the One”, the Merseybeats U.S.A. “Nobody Loves Me That Way”, and two bands I’ve covered on this site, the Rugbys and the Nite Owls.

the B side on you’ll come back is…. Nobody does me that way… it is also the B side of 30 second lover. There are different band members on 30 second lover. Terry Adams only plays on… stop look and listen…. he was only in the Mersey beats for the summer of 1966.
