Ring exchange during a song

So we are writtting our own vow and obviously going to speak those where everyone can here. But the ring exchange is being done a little later. My matron of honor is singing a solo that is beautiful and I think would go awesome over our ring exchange. With the pronouncement and kiss after the song.

But it that means no one will hear the words over the rings just see the actions.

Am I insane to condiser this? Should I do the ring exchange, then solo, then pronouncement and kiss of should I do the solo and then have the rings be the very last thing...
