[Leica] What to use for concert photography?

[richard-lists at imagecraft.com (Richard Man)]

I will be shooting a few taiko concerts officially. This means pre- 
and post- performances (hope to get some good candid shots), shooting 
from side of the stage and in front during performances. No flash of 
course during performances. Currently, my longest lens is 90/2 M and 
that won't work on the R-D1.

So I am thinking (for other reasons also) to pick up an Oly E-3. The 
zoom lens should come in hand during the various composition 
possibility of the performance. I think ISO 1600 should be sufficient 
for F2.8 /3.5 shots. The noise on the E-3 seems ti be OK and the 
in-body stabilization should help.

The other alternatives is to get a M8 and a 135mm, but a) it's way 
too expensive, and b) I would probably need to put a wide angle lens 
on the R-D1 to cover the other end, so it's definitely not as flexible.

Suggestions? Thoughts?
