We've been asked to perform at a wedding of a family friend in two weeks. I decided we would only do six songs (30 minutes roughly). I'm confident the singer, guitarist, and myself are ready for the performance and even the drummer but it seems he has a lack of faith in his abilities. I'll be the first to admit that our drummer is average at best but the rest of us can more than make up for it. Even the few times he messes up in the six songs it is not noticeable enough as the rest of us got it down good. I think we're ready however our guitarist won't perform if the drummer says no. The singer and I are on the same page. I told him this Thursday at band practice we would make the final decision. I guess what I'm looking for advice here is how best to reassure him that even if he makes some mistakes it will be okay? The singer and I tend to play good parent/bad parent with me being the bad parent, making sure everyone has their notes down and pointing our any flaws in our performance. That being said I do get the sense that I intimidate the drummer at times and come Thursday I don't want to act that way again. I haven't even told him that we'll probably be performing in front of 200 people for that matter. This is going to be among friends so I don't want him to worry too much if we mess up, plus it will help deal with his anxiety when we actually perform in front of strangers. Any advice guys? Thanks.
