The hip-hop foursome, Black Eyed Peas, will soon become a five-piece with the addition of newest member, 73-year-old Harold Perkins.

The Peas, who started as a diverse threesome — a black guy, a Mexican guy and a Filipino guy — added white, female singer Fergie for its 2003 release, “Elephunk.” Fergie, Stacy Ferguson, expanded the Peas’ mainstream appeal to whiter audiences with her rough streetwise look, which she originally crafted as a child on the Disney Channel’s “Kid’s Incorporated.”

With the addition of spoken word artist Perkins to the lineup, the Peas plan to reach two more demographics with one man. Not only will Perkins’ wrinkly smiles melt the hearts of the soon-to-explode senior citizen market: This old fart loves NASCAR. That’s right, Perkins will also appeal to the newly labeled “NASCAR Dads.”

The additions of Fergie and Perkins weren’t the only times the Peas reached out to underdeveloped markets. The group celebrated the mentally disabled with its song, “Let’s Get Retarded.” It then switched up the lyrics and title to “Let’s Get It Started” and sold the song to the National Basketball Association to use during the 2004 playoffs.

The Peas newest album, “Monkey Business,” drops June 7. The first single will showcase Perkins and is titled, “These pills is getting me stiff fo’ NASCAR.”
