There may have been Karaoke

 I can neither confirm or deny that any karaoke has been sung.

However, IF such a thing was ever done, my go-to songs would be:

At This Moment, by Billy Vera. Love this song. Might have been sung at midnight in Key West. All I know for sure is the next evening, while walking on Duval Street, someone stopped me on the sidewalk and said, “Karoke guy! You killed it last night!” Very confusing. ;-)

…Baby, One More Time - Bowling for Soup. This catches everyone off guard. No one has the Bowling for Soup version, so you have to sing it to Britney Spears, which makes it fun.

Bad Romance - Lady Gaga. Just a fun song. By the time you get to the last stanza, everyone is singing with you.

Other notables are Sweet Child o’ Mine, Guns and Roses; Piano Man, Billy Joel; and Sweet Caroline, Neil Diamond.

But that’s just a guess…
