Do you hear what I hear? It's the sound of Broadway stars caroling as Broadway.com celebrates the holidays with a seasonal flashback each day. Broadway audiences now identify Gavin Greel as shaggy Hair hippie Claude, so it's easy to forget the Tony nominee cleans up rather nicely! Creel looks quite dashing in the 2003 TV movie Eloise at Christmastime, which found the actor working at the luxurious Plaza Hotel. Based on the popular children's book series from Kay Thompson, the movie follows the mischievious title character who lives "on the tippy top floor" of the famed hotel as she celebrates the holiday season. Creel, who played hotel waiter and Eloise's close friend, Bill, treated the adorable blonde to some festive caroling by taking to the piano and singing "Winter Wonderland." Take a look below!
