Some info on the Kama label & Chadwicks Recording studio on GARAGEHANGOVER.
Kama was based out of Utica (which is in the middle of nowhere in New York state -- to the east of Syracuse). Chadwicks studio was located just south of Utica, in a place strangely called Chadwicks. So I'd guess the group (white ?) were from that area. They cut other sides for Kama, each in conjunction with other singers (Danny Bowens & The Avengers "Lavender Blue" being the best of those other cuts). Kama Records was operated by a Stanley Markowski, who had a pressing plant in Utica. Seems his pressing plant was sometimes not working to full capacity, so he hooked up with mob members & pressed up bootleg 45's for them in the early 60's. The mob ran numbers rackets across the US and were always looking for 'legitimate businesses' through which they could launder their money -- maybe they financed the building of this pressing plant. Stanley Markowski, died in 2005 at the age of 82. He had lived in Erieville most of his life (just over 30 miles south west of Utica), working mainly as an auto mechanic and machinery mechanic. Being a machinery mechanic would have been handy if you ran a pressing plant. He'd have been in his late 30's when the pressing plant was in operation.
The Mr. Genius label is out of Philly & that 45 track was almost certainly cut in Philly.
There were quite a few groups who took the name of THE AVENGERS -- I guess these two were different groups.  

Published in the new edition of SOUL UP NORTH; out this coming Thursday / Friday ... 
CODY MILLER; MUSIC MAN: . . . . . . If you went crate digging in rural Louisiana, you could expect (if you were lucky) to find 45's on labels such as Tamm, Jin, La Louisianne, One Way, Master-Trak, Maison De Soul, Bounty, etc. If you unearthed copies of the right singles on these labels, you'd consider yourself to be blessed. However, the guys involved in laying down those tracks (generally) had no idea that the results of their recording studio efforts of 50 years ago have become real collector's items.  ETC. ETC. ....

When "Dance To The Music" came out here it was massive in UK soul clubs, right from the off on Columbia in March 68. 

I'll see your first blue & raise you one ...
This record company was based in north Ft Lauderdale about 5 miles sth east of our Florida house. I seem to recall a local radio stn was also based in this area back in the 60's / 70's (long gone now). It looks like a simple small office & lock-up garage affair. No doubt just had a desk + a telephone & the stock was kept in the garage area.
