Cena and Jericho are both WWE main-eventers who've tried it, but don't forget about Lillian Garcia. I have her album, which is recorded in Spanish of all things. It's not bad, but it's not intended for mass consumption.
One of the first professional wrestlers to try his hand as a musician -- or was he a musician who tried his hand at pro wrestling -- was "Freebird" Michael Hayes. Back in the early '80s, he wrote and recorded the group's entrance music "Badstreet U.S.A." The Freebirds' popularity helped give the song some traction at Southern radio stations, and Hayes would occasionally take short periods of time off from the ring to play gigs throughout the Southern states. It was never a "break-through hit" or anything of that nature.
Another person who parlayed a career in the music industry into success in pro wrestling is "The Mouth of the South" Jimmy Hart. He got his show-biz start as a teen, performing with The Gentrys, a "boy band" which recorded the million-selling single "Keep on Dancin'." The group would have probably had greater success if their label, Stax Records, hadn't gone bankrupt.
Later in life, of course, Jimmy became a legendary pro wrestling manager. But at the same time, WWF also utilized Jimmy's musical skills, employing him to write some of the best-known wrestling entrance music of the 1980s. In addition to writing entrance music for talent he managed like The Honky Tonk Man, The Nasty Boys and The Rougeaus, he wrote a piece of music almost any fan over the age of 15 knows: Shawn Michaels' "Sexy Boy" theme!
Another performer it might be easy to forget had a foray into the music industry is Hulk Hogan. I remember early in his career with AWA (in the era just before jumping to WWF), he was profiled in a few music magazines for playing bass guitar in a few bands. At one point, he teamed up with his good buddy Jimmy Hart to put out an album. I'm pretty sure his wife Linda was included in the group as well.
