I can see how you would be disapointed hearing bob sing Loser. The first loser I heard them do was this year at red rocks and i would have been really bummed if bob sang it. There is just some songs he should sing and some he should not. Its like if he were to sing rueben and cherise... just doesnt work IMHO!
Bottom line is theres a lot of politics involved that none of us will probably ever understand... I could sit and critique the band all day (literally) but in the end they still sound amazing and im just happy they are still playing and happy I am able to be apart of it all!
Forever and ever Grateful!!
