"Getting Better" by Lennon/McCartney was recorded by the Beatles on the album Sgt. Pepper's Lonely Hearts Club Band. You can probably get the lyrics from the Beatles' official site or from Wikipedia. (Don't know nuttin' about Osbourne.)
My late brother wasn't big on top 40 urban contemporary music but he loved Osbourne's "Baby Stay With Me Tonight." That was his cut! His jam! His song! Whenever I hear it, I think about him and can't help but smile.
