1967 – The Unicorn Coffee House, 815 Boylston Street, Boston, MA
Thanks to Ray Paret for the following info (The J. Geils Blues Band were signed to Amphion Managment, ran by Ray Paret and David Jenks).
The picture from The Unicorn below shows the drums from a band called Underground Cinema that eventually became The Ultimate Spinach and the drummer in that group at that time was Keith Lahteinen. I have no idea who the other two guys playing with J.Geils are, but I would guess that this photo is from 1967 before July or August as it was during that summer that my partner David Jenks and I signed Underground Cinema and changed their name to Ultimate Spinach.
Thanks to Valerie Klein for the photo.
1968 – January 23-24-25-26-27. The Catacombs, 1120 Boylston Street, Boston, MA

The J. Geils Blues Band Performing On Cambridge Common. circa 1967/68
The first photo is from Jay’s ‘New Guitar Summit’ DVD Live At the Stoneham Theatre. The photo shows Jay with Magic Dick in the background. Taken at Cambridge Common.
Found the second photo in Googles archive. Unfortunately the site it’s from no longer hosts the photo. The drummer looks like Keith Lahteinen who left The Ultimate Spinach late 67 early 68 to join the J. Geils Blues Band.
1968 – Amphion Managment Promo Photo
The “fourth” guy (in the photo below) is Keith Lahteinen, but he was the original drummer in The Ultimate Spinach and in fact recorded their first album on MGM. Keith quit Ultimate Spinach to join J. Geils (late 1967 early 1968). It was later that year that David Jenks and I decided that the band needed more so we asked Peter and Stephen to join after the Hallucinations broke up and that’s when the band really started to cook! Keith was a great drummer and great blues singer but to make it the band needed more of a rock and roll edge!
