Also, and I'm hoping Scotty chimes in, wasn't RME mooted, and in a rare instance, shot down by James? Do we know why? "Lyrics" are the obvious answer, but there's nothing there that is truly controversial, or at least more controversial than some of the other things that they've performed in the past.
Yes, it was RME that MP proposed and JL didn't want to do it. No clue as to why. Perhaps it's just a song that for whatever reason, JL doesn't like or maybe even hates. Not any different from anyone else (one man's trash is another man's treasure).
Seriously though I am in the minority and don't really like when bands do covers, UNLESS they really make it there own.
This is the one thing I didn't like about DT's covers - they almost always were carbon copies of the original. And by that, I'm not saying they have to change everything around - but it should sound like the band doing the song, not them doing a cover. A perfect example of this is VH doing You Really Got Me - aside from the solo, the song stays pretty close to the original, but if you were to play the song for someone who didn't know it was a cover, they probably wouldn't figure it out, because it sounds like VH.
The one cover DT did that really felt like they made it their own more than any other was their version of Rush's The Necromancer. OTOH, their cover of Pink Floyd's Echoes sounds like DT doing a cover of PF - especially JL's muted vocals imitating Gilmour's.
