Since the 2005 Halloween season, former drummer Johnny "Vatos" Hernandez has regularly put together an Oingo Boingo tribute band for performances at different venues, mainly throughout Southern California and Arizona, including The Grove of Anaheim. Initially billed as the "Johnny 'Vatos' Tribute to Halloween, Featuring Former Members of Oingo Boingo," Hernandez eventually titled the project Boingo Dance Party and then Oingo Boingo Former Members. The group is joined intermittently by former Oingo Boingo members such as Steve Bartek, Carl Graves, John Avila and Sam "Sluggo" Phipps, while vocals are usually provided by singer Brendan McCreary, also known as Bt4.
