canned heat classic or dud?

I listen to a lot of 60s music, but I've always been put off listening to Canned Heat (I did hear their record with John Lee Hooker). Just looking at their dreary album covers gives me enough of the blues. Even though I suspect they're probably better than Quicksilver Message Service or Country Joe and the Fish, both of whom I have listened to...

Heat fans should look for an obscure made-in-Florida indie film by exploitation director William Grefe called The Naked Zoo (1970) which features a scene of the band playing “One Kind Favor” at a “house party” - actually a separately shot sequence later inserted into the film’s party scene. It’s the Harvey Mandel lineup. Also the film stars Rita Hayworth near the end of her career. Weird to think of Canned Heat and Rita Hayworth appearing in the same film.

I posted about it upthread, however the youtube of them performing seems to have disappeared.

...yet I've started listening to Ten Years After! Can I resist the lure of a copy of Boogie with Canned Heat from the same library?

The record with John Lee Hooker is awesome
