Advance Preview With Christmas a day away, Meg (Brittany Snow) and dance partner Jimmy Riley (guest star Jesse Hutch) are voted one of ""Bandstand's"" favorite couples landing them a date under the mistletoe for their first kiss, which hurts her budding relationship with Luke (guest star Jamie Elman). Meanwhile, JJ (Will Estes) receives an early Christmas present with his acceptance into the University of Notre Dame, which prompts him to reconsider his break-up with longtime girlfriend, Beth (Rachel Boston). Elsewhere, Jack's (Tom Verica) military expertise is called upon when a local boy serving in Vietnam goes missing and Henry (Jonathan Adams) looks for a raise during the store's holiday rush.
