I used to use a music stand right on stage next to my mic stand.
The band I'm in has several compicated medley's and it was tough
to get them committed to memory at first.
There's nothing wrong with having it on stage. If you can put it
off to the side, that's even better. I don't think it even matters
what type of music you're doing, a music stand has it's place in
music performance. If anything, I would think people would see
you as wanting to be professional and do a good job.
I've since moved on to a mic stand mounted smaller version.
Similar to this one, however, mine attatches to the stand, not
the boom:

Anyway, I say go for it. It's just another tool for you to use
to do your job, nothing to be ashamed or worried about.
