On the CD compilations the recent Land Of Sensations & Delights:
with Summer Dream by Mournin' Do:
and Psychedelic Crown Jewels Vol 3:
with Silhouetted Summer Dream by Group Therapy
is clearly the same song in different performances.
One of these is a cover of the other, or maybe both are
a cover from some unknown source.
The CD liner notes for the Mournin' Do version says it was
only distributed to radio stations and is dated as Oct 1968
on the White Whale label. I'm missing the liner notes for
the other CD so I don't know if it says anything about
Group Therapy. The 2010 edition of the book Fuzz Acid And
Flowers doesn't list this Group Therapy just a different album
issuing group called Group Therapy with just a note that at
least three other groups are also called Group Therapy.
I mention this not that I'm thrilled with the song, but
that I'm very familiar with the Group Therapy version as
this is one of the first sixties CDs I bought and I
listened to this downbeat CD many times. If you like
depressing sixties garage music Psychedelic Crown Jewels
vol 3 is a good one.
