Boyz II Men kicked off WrestleMania XV with their rendition of America the Beautiful. The R&B group was one of the hottest acts around at the time. The group from Philadelphia provided a melodic beginning to the event.

Pete Rose
Rose came out dressed as the San Diego Chicken during WrestleMania XV. Pete Rose is one of the greatest baseball players of all time, as he holds the all-time hits record, but he is probably best known for betting on and being banned from baseball. This marked the second year in a row that Rose was Tombstoned by Kane.

Isaac Hayes
Hayes had ringside seats for the event and performed at the WrestleMania Rage Party the night before WrestleMania XV. Hayes' lent his unmistakable voice to the theme song of Shaft, and it earned Hayes an Academy Award for Best Original Song for a Motion Picture in 1971. Hayes latest claim to fame is as the voice of Chef on the hit animated series South Park.

Vinny Pazienza

Pazienza was the guest referee for the Butterbean vs. Bart Gunn Brawl For All Match. Pazienza is considered one of the greatest Super Middleweight boxers of all-time, going 46-9. Some of his more memorable wins have come against Joe Frazier and Roberto Duran.

Kevin Rooney
Mike Tyson's former trainer was a guest judge for the Brawl 4 Fall between Butterbean and Bart Gunn.

Chuck Wepner
Wepner served as a ringside judge for the Brawl for All Match. Wepner once wrestled Andre the Giant and once boxed Muhammed Ali, and the movie Rocky was based on Wepner's life.

Butterbean
Butterbean faced Bart Gunn in the Brawl For All. Butterbean was an imposing 365 pound professional boxer. Bart Gunn surprised everyone when he won the WWE's Brawl For All Tournament, but he met his match with Butterbean, as the heavyweight knocked out Gunn almost as soon as the bell rang.

Big Pun
Big Pun, who had ringside seats for the event, was the first Latin solo rapper to achieve platinum status. Perhaps his most well-known single was Still Not a Player. He performed at the WrestleMania Rage Party the night before WrestleMania XV.
