I love ron, but I think he is unnecessary. Listen to richards solo's... him and robin can totally handle the guitar duties.
Close, more like Robin is the one that is un-necessary. An 87 year old woman could listen to Bumble, Richard and Robin and pick Finck as the weakest of the 3. So if by your logic we need only 2 guitarists, based on pure talent Finck should pack up his guitar and go home.
