Sweet Thursday was a short-livied British rock group that only released one album. The group was comprised of a bunch of studio session players, most notably Nicky Hopkins who worked with The Beatles and the Rolling Stones.
The track “Gilbert Street” (named after a place in London) opens with a nice, mellow drum break (love the snare!) and then extends to a 10 minute prog-ish/folk-ish/rock track.
Note – the 1st pressing of the record came out in 1969 on a small imprint Tetragrammaton. The label folded and not many copies were produced. After gaining a little popularity, Columbia picked up the record and re-released in 1973 under the Great Western Gramophone label. Full disclosure, I have the 2nd pressing from 1973 🙂
