It's no newsflash that playwrights often find inspiration in their personal pasts, and use young leading characters as theatrical alter egos; if you want to better understand Tennessee Williams, listen to Tom's monologues in The Glass Menagerie, or watch Edmund's scenes in Long Day's Journey into Night for greater insight into Eugene O'Neill.
When I was in seventh grade, my chorus class took a charter bus up to Chicago to see Joseph & the Amazing Technicolor Dreamcoat. From a row near the back of the theatre, I watched the vibrant speck that was Donnie Osmond belt out the tunes "Close Every Door" and "Joseph's Coat." On the return trip home, while the chaperone mothers murmured in fascination over the dark-haired leading man, we chorus students amused ourselves with a Joseph sing-along. The music was just that unforgettable and appealing, even to our usually unimpressionable teenage minds.
