My fiance and I are having his cousins who are professional jazz musicians sing solos at our ceremony after the readings. I am not really sure what we're supposed to do while they're up there singing. We're getting married in a garden/courtyard setting outdoors. Do we stand next to each other, sit down, move a little? I am not really sure and want to avoid looking awkward. The songs we're having sun are "At Last" and "Wink and a Smile."
