We are having a short civil ceremony. My sister sings opera semi-professionally and I was going to have her sing something short (2-3 min max) during the ceremony. Does this risk making it feel like a recital? Or is it AWish like my family is showing off my sister? If it were a religious ceremony we could just have her do it during communion or something and it would fit in, but I'm not sure how it works with a secular ceremony. Thoughts?
