I began to amass my music collection long before their even WAS a Rock and Roll Hall of Fame. I dobn't know; maybe that somehow explains why so many of my favorite rockers still aren't in the hall and probably never will be. Or maybe Rock Hall chieftans are too frequently morons.

This isn't a new bone for me to chew on, so who am I complaining about now?

Why, the British hard rock band UFO, headed up by vocalist Phil Mogg. Jeez, this is a great, great band. Well, see 'em now — for free, I might add — when they appear Saturday in the Mohegan Sun Wolf Den. Mogg has decided to call it quits and rolled out this version of the group for the "Last Orders 50th Anniversary Tour."

Expect excellence despite the fact guitarist Michael Schenker won't be there. Mogg is still in great voice and has long-time UFO road vets with him. They'll parade the favorites, including "Mother Mary," "Love to Love," "Cherry," "Only You Can Rock Me," "Rock Bottom," "Doctor Doctor" and, of course, "Lights Out," the latter of which I hope is playing when someone torches the Rock Hall.

UFO, 8 p.m. Saturday, Mohegan Sun Wolf Den; free; 1-800-745-3000.
