I read an article about pop artists using pseudonyms last weekend in the
Sun-Sentinal (Miami-Ft. Lauderdale). It was in response to the Chris Gaines
album(Garth Brooks).
Paul McCartney is "The Fireman"
I checked out some real audio at cdnow or amazon, so can you!
One other of note was Elvis Costello as "The Imposter", a protest singer.
