I have a ped for that it called A One Man Band he shows up on time and does not talk back and keeps all the MONEY!!!!!!!
Ron, having the arranger has kept many players still working steady, whether as a soloist or in a duo, or even a trio.
In your case, being a vocalist as well as an arranger player gives you the edge over those who don't sing...there's a lot more work opportunities for you than those of us who just play.
I look at the whole arranger thing this way...you do what you have to do...if someone doesn't like it...that's their problem.
I'm considering putting together a duo in the new year, with a singer/guitarist and so far, it's looking good.
