Doers anyone have information on what appear to be other labels affiliated with K-tel in the 70's.

There are a number that appear to be part of the K-Tel "family", the record numbers fit into the K-Tel numbering scheme, and the companies are all in the same general area of the twin cities (in fact some even have the same address)

Some of the labels in question:
Commonwealth Music
Era (made by Dominion Music)
Lotus
Imperial House
(There may be others)
Curious how these may all fit together, I know there were some financial shenanigans going on in the late 70's which may have been part of it, (and helped lead to their demise in the early 80's, although I understand now they're back in CD's)
