"Drunk Last Night" was written by Laura Veltz and Josh Osborne. When they wrote it, Osborne was on a hot streak. Veltz, trying to impress him, arrived at their songwriting session with what she felt was "a massive idea" for a song.
Veltz recalled to The Tennessean
that her suggestion wasn't working out, so she said, "Josh, I'm sorry, buddy, but I got a little drunk last night and I'm hazy." Osborne immediately realized he throwaway comment was a song idea right there; together they started writing "Drunk Last Night," which would become a country hit for the Eli Young Band.
