i have a big gig coming up in a few months, well hopefully.
and i think of it this way,

"if they dont want to see you, they wouldnt pay the money, and if they are disapointed then thats their own fault."

and listen, you can play guitar and sing, thats an amazing skill to have, and alot of people take it for granted. I have a guitar, and i sing in a band, but it would take me along time to do both.

if you want my advice on getting your band to help u say more, say like

"this is our drummer [name]."
just, be yourself
everyone loves you when you be yourself.
and i wish you goodluck
