One you may not here very often, Elvis did also record a completely tasteless version of 'Old Macdonald'. The king talks meat, or rather sings about it. Probably the worst song of his film career. Truly awful. Veggies beware."

I don't know where in the world Rossey lives, but I con't think the "Veggies beware" is directed at carrots and onions.
