The Tragically Hip are going to be in Rock Band through the RBN. So far, the only song in testing is "Blow at High Dough" but you have to admit, that's pretty sweet. Especially for a start.
I did think a bit and realize what the issue with OLP is. The label owns rights to the masters I believe....which means 2 things.
One, OLP could do a re-record for older songs (*ahem* Spiritual Machines/Clumsy tour live tracks, or surely a rehearsal was well recorded

or two, if the band were willing, we could at the very least get some stuff from Burn Burn (and I would LOVE that), White Flags and Monkey Brains for the win!
I really wish the band would at least give it a try with ONE song, just to see how it goes.
