In addition to the great design work on the cover of their Child Is Father to the Man album, where each band member was shown with a puppet version of himself sitting in his lap, this is one of those efforts from the early days of modern music that still stands the test of time. In fact, it was way too good for its time. I don't think this album sold near as well as the later, more schmaltzy work, with David Clayton-Thomas.
You should give this a listen if you can get your hands on it. Steve Katz was the guitarist and vocalist, along with Al Kooper who also played the keyboards. The rhythm section was excellent, with Jim Fielder on bass and Bobby Colomby on drums. A future jazz all-star, Randy Brecker, did the trumpet work. It has an Overture opening written by Al Kooper, and then several very good songs. My favorites are Morning Glory, "Without Her" (written by Harry Nilsson), "Meagan's Gypsy Eyes" (a Katz song), and "House in the Country" (Kooper). It came out in February of 1968 and I saw them play this entire album live in 1970. They did a fairly respectable job with these quite complex arrangements.
