Have a nice glass of wine before you go out - hahahaa.
But, if that isn't something you'd want to do, I wouldn't worry. You'll be with other people, and if it is putt putt or bowling, you won't have to worry about sitting next to him and feeling uncomfy. Usually fun first dates like that are always great, because it's just hanging out.
I mean, he's being set up with a DG, what more could he ask for?
Good Luck!
