I was going to chime in with my 2 cents but it's all been said and more.
But... that won't stop me.....
Embrace your obscurity on the stage. Be the "Swiss army knife" (as Beagle put it) of the band. You play the strings and horns because quite matter of factly, no one else can do it. Drums, guitars, and bass certainly can't. So you play it. It's not the glamorous life, but there's a lot to be said for being able to walk around the venue or down the street without being mobbed by adoring fans or chased by paparazzi. (not that I would know how that is)
If you want to be famous..... get the chops and skills to be among the Rick Wakemans, and the Elton Johns, and the Liberace's of the world. Really if you look at it realistically, even with guitarists and drummers and bassists, the same thing holds true. Only a relative few really are recognizable from their playing styles considering how many there are. Eddy, Steve, Jimi, etc.... and it's only because they have earned that esteemed place through their skills and chops.
