What would you do?

My vote would be to also let him go to the concert. He's not a "little boy" any longer and, as hard as it is for us parents to accept (mine are 16 and 13), there comes a time that doing things with their friends is more important than anything else. If your mom lives in town, then he can visit with her anytime - I would view this differently if she lived out of town and you were traveling to spend the week-end with her. As your husband said, he's only going to be young once! If Saturday won't work, take him Friday night or Monday night.
