Teen Titans Vol 1 #46

The Fiddler, having left the ranks of Earth-Two's Injustice Society, wreaked havoc at the scene of an Earth-One rock concert, and tangled with Mal and Speedy, while at Titans HQ, Robin proposed his recent antagonist, the Joker's Daughter, for membership. Meanwhile, promoter Bernie Michaels sponsored a "Battle of the Bands" concert featuring Peter McCarthy and the Flyers with the Woodworkers, although the two groups professed antagonism to each other while never having met. When the Fiddler appeared to have kidnapped both groups, the Titans, with the aid of the Joker's Daughter, battled and captured him, only to discover that the Flyers and the Woodworkers had always secretly been the same people in different guises and had arranged their own seeming abduction to avoid having to appear in both identities simultaneously.
