But I read it in black & white!??   used to be the mantra before the www.
I have seen many fer-instances where a song is "lyrics & music by John Lennon" because Lennon was the first name in "Lennon and McCartney" and there is room for only so many characters to be typed in following "lyrics & music by . . .".   Even when the song was actually said by Lennon (&/or McCartney, Harrison, Starr) that it was in fact written by George or Ringo, or Paul!

   Don't believe everything you "see" on cyberspace! Except the recent byline about Elvis being alive & pregnant by aliens.
