Ever heard his early works with Marc Benno as the Asylum Choir? Their first album was great, the second was pretty good, too.
Go to
to hear both.

i had the 1969 album and had the '68 album as a bootleg back in the day...
these albums are very good,but significantly different than Leon's other albums & his prior work.
what a genius!
so sad-Leon was special...
watch the record bins, my new great find source is the weird ones at antique stores....
coincidently found Asylum Choir II a couple months ago, perfect, 4 bucks.... 
Leon was a giant and Asylum choir had some cool stuff..
Interesting material about all that in this Benno interview I did a few months ago:
