Different band members have different aspirations.
What I hear, is the guitarist wants the group to spend money, yes it takes money to operate a band. If nothing else, you need copies of the new music. (Is someone going to fax the copies at work?)
To me, band means partnerships, and the need for a business model and therefore liabilities.
Before, forming a band, I think the group needs to jam a few times, work over a limited group of songs, and find out if they are compatible with one another. I believe a band is a highly personal relationship, and needs to be treated as such.
I would write all people involved and make the statement. "The group is not ready to form the personal relationship necessary to form a band. It probably too late, but next time, you are looking on forming a group to play music, Discuss the personal relationships that bands require.
Always ask what is what is it going to cost me?
