These demos were recorded in March 1973 at Planet Studios in NYC with Paul Nelson producing. For my money, these recordings are the best the Dolls ever did.
There are a total of 22 tracks in the demos but most releases contain less. The only place to get them all is on the double LP 7 Days Weekend. The recent release, A Hard Night's Day, has almost all the tracks and it has great sound and a good booklet.
There are 2 other demo recordings from the Dolls: demos #1 and demos #2.
These demos have been released on:
