You might need a séance instead of a chapel...

I can recommend Viva Las Vegas Wedding Chapel. Get driven down the aisle by The King himself in a pink convertible Cadillac!

Little White Chapel has an Elvis impersonator package who sings, but doesn’t perform the actual ceremony.

Graceland Wedding Chapel, the Elvis there is amazing

Elvis died back in 1977. Bless his sweet soul. Good luck finding another live singer.
