Montrose were the first live band I ever saw - supporting Status Quo on the 1974 tour. I saw them at Glasgow Apollo and the whole thing just blew me (at 14 years of age) away. Fantastic and made a huge impression on me. I had the first two albums on vinyl through the remainder of the 70s, but as with so much of my stuff they got lost and I don't know what became of them. I still have a few of the songs on my ipod playlist today and they stand up as well as they ever did. Ronnie was awesome and one of the best guitarists of that era - way ahead of his time, and Sammys' voice still sends a shiver of delight down my spine.
Not familiar with any of the Gamma stuff - was it Davy Pattison who sang for them....?
