Keep in mind Grand Funk was ALL Mark Farner as far as talent. And of course, he got screwed by the lawyers and ex-bandmates and no longer can even use the name when he performs.
That's a shame. It appears the greatest rock artists didn't have a prayer. If they didn't get screwed one way, they got screwed another. The best example I always remember is how the record label forced Rush to make so many mediocre albums, another crying shame, since their core albums are legendary.
An Interview with Mark Farner
Review: I realize that the subject of Terry Knight is a tender one because
of how much money he appropriated from the band, but was your relationship
with him a complex one?
Farner: I told Don Brewer before we went into this thing that Terry was a
con man, a rip-off artist and that we're gonna get screwed. Brewer said
that was better than sitting in Flint, Michigan. And that's pretty much it.
There was a big interview with Terry recently in Discoveries magazine and
his character comes out so much in that piece. I read a little of it and
had to vomit.
