A director pal asked him if he'd appear as "the hero guy" in Seger's Night Moves video, opposite Melrose Place star Daphne Zuniga, and LeBlanc signed up.
But it turned out the rocker was a fan of his then-new comedy show and he invited the actor to join him for a drink before the shoot.
LeBlanc recalls, "It's at this drive-in movie theatre... and I'm in this little box and they knock on the door and say, 'Bob Seger would like to talk to you in his motor home...,' so I go in there and he's this really nice guy and he's really humble and he whips out a bottle of tequila.
"Cut to about an hour and a half later, I'm hammered and he's hammered and my friend that was in it (video) with me, he's hammered... You can kind of tell in the video I'm a little (drunk)."
As well as LeBlanc and Zuniga, The Big Bang Theory's Johnny Galecki also appeared in the 1994 promo.
