Marlton's Randy Alexander is used to staying behind the scenes, but the music publicist is schuleded to be on CBS' "The Early Show" in the 8 a.m. hour Thursday in a segment about Michael Jackson memorabilia. An appraiser will be on set and Alexander will display pictures and autographs from a 1972 chance encounter with Jackson and several brothers in the game room of a Washington D.C. Hilton where the Jacksons came in to shoot pool as Alexander, on a family vacation, played pinball.
