Sometimes your favorite song (and a little ‘liquid encouragement’) can make you do crazy things. That was the case recently at a Bryan Adams concert when one fan couldn’t help himself and jumped on stage to sing ‘Summer Of 69’. But as you’ll see in the video below that’s now gone viral, the Canadian singer doesn’t flinch. Yes, Adams looked annoyed, but with security swooping in to remove the overzealous fan, the singer gracefully kept the party going! True, after a few drinks it might be tempting to pull such a stunt, but definitely not recommended~
