Rey Mysterio as a musician
Pro-wrestling fanatics are extremely fond of his Booyaka 619 theme song. But only a few people know that Rey Mysterio himself sang that song. Along with rapper Mad One, he performed in the original version of “Booyaka 619”. Since 2005, he is using this as his theme song in the WWE. Later he lent his voice for a rap song, called “Crossing Borders. WWE Original included this in their list. WWE also used him in the official theme song for the 2004 No Way Out pay-per-view.
