So I have 2 friends that are in the same band, and have graciously offered to play at my wedding. Of the 2 friends, one would definitely have been invited anyway, the other one, probably not (due to money/ food constraints) . There are also 2 other members of the band to which I don't really know. I wanted to let the close friend know he would have been invited even if his band wasn't playing at the reception, but I wasn't sure if that would be rude to the other members of the band?
I was also considering not sending them traditional invitations, but maybe just some kind of note saying that even though they are in the band, I still would like them at the wedding as guests, and spent at least part of the reception as mingling and eating guests? Our wedding is not very formal, could I just send the good friend a message on Facebook letting him know all this, and tell him to let the other members know this as well?
