What qualities, (not qualifications and experience) does one need to manage a well established local band?

my husband is good friends with a guy from a Grateful Dead cover band that is very popular in the greater Boston area. He commented to my husband that they need a manager but don't want to give up "control". I have no issues with control, I believe in what I already know of them. they are good friends and get along well so my position on that is one of a democracy or vote. Obviously, I am interested but haven't a clue the details of the job. What I do know, is that I love the music and the band, I'm very persuasive and persistent but not obnoxious, and can talk any body into almost anything. I am a night owl, do not like "structured" jobs, and don't care all that much about a huge salary. I am also intelligent, motivated and enthusiastic. I asked my husband to ask without mentioning me, what they were looking for in a manager, before he replied to his friends comment in email. He was hesitant, and now it would seem random to ask. It seems like he was either afraid I could not do the job and it would affect the friendship, or has no faith in my ability, but I'd like not to think that is the case. Can someone tell me the characteristics (and ballpark pay) of a popular local band, as well as the personality qualities of someone who could effectively manage this band? They are all a bunch of fun loving guys, two of whom attended and played at my wedding reception.
