Members?

Few weeks ago, M got offered a job in 7-8 restaurant as a guitarist. Last night he asked again for a serious offer, and he got a reply.

Now he's faced with a situation; to play alone, or to have someone beside him singing/playing. M was grateful for the opportunity to play in front of people again...but how will he proceed with these questions the 7-8 owner asked?

 "...equipment, extra members, date/time, cost, when.."

Now where's his brother when he needs him...
