UFO blew every one of those bands , except for Van Halen, off the stage. A really great but unsung 70’s metal band. I saw them Both before and after Michael Schenker. Shenker made them. Their 78’ tour was incredible. I saw them with Blue Oyster Cult and it was my favorite concert of all time. Both bands were at their zenith.
I have to admit that I have really never checked out UFO before. Not sure why other than living in a real small town in southeast Nebraska in the late 70’s didn’t expose me to a lot of music other than what KFMQ in Lincoln played. I will check out some UFO on Apple music and let you know what I think. I really enjoy checking out new (to me) music. Especially since there is not a lot out there that is new that is good or even tolerable.
