We were married 6 yrs ago also had like a karaoke session at the wedding. We named our tables with song titles all containing the word "love", eg no 1 was "Love Is
in the air" table 2 "All you need is love", etc. The kids table was "Can you feel the love tonight" from the Lion King.
We printed the first line of each song on the back of the card and then the MC asked each table to sing as much of the song as they could. We had a bottle of champagne
for the winner. It was fantastic! Everyone loved it. That made our wedding a bit different!
