Jack glanced over at the mention of 'perk' and smiled widely at Greg's movement, clapping his hands, "Ha cha cha, dear!" Jack got down from the stool and grabbed for Greg's hand lest he get lost in the crowd and wouldn't be able to find his six foot something friend with the Dee Snider hair.
Once they were out on the floor, Jack recalled why he didn't go dancing often and it wasn't because he could have just as much fun back at the flat with Jules, being his private dancer, Tina style-no, it was because how close everyone seemed to need to be in a club. He stayed close to Greg but did perk up over the song being a weird techno version of Joplin's 'Take Another Little Piece of My Heart', grinning like a fool over it.
