The real star of the 1980 Police Academy films was Michael Winslow aka "The Man of 10,000 Sound Effects." (See below.) Sound imitation is truly his life's work and there is nobody better. Above, Winslow joins Norwegian folk megastar Odd Nordstoga for a rousing rendition of Led Zeppelin's Whole Lotta Love with Nordstoga playing acoustic guitar and Winslow on everything else.
