Weird Al Yankovic; A Musical Hero
Alfred Matthew Yankovic
Born October 23, 1959), better known by his stage name "Weird Al" Yankovic, is an American singer-songwriter, musician, parodist, record producer, satirist, actor, music video director, film producer, and author. He is known for his humorous songs that make light of popular culture and often parody specific songs by contemporary musical acts, original songs that are style pastiches of the work of other acts, and polka medleys of several popular songs, featuring his favored instrument the accordion.
