Two from my wedding reception, BTW: Wonderful Tonight (first song; my fiancée had had a bad play this when I proposed to her, so it seemed appropriate), and My Valentine (my wife had, on an earlier romantic evening, called Windy 100 FM's request line to request it; they said they'd play it, but my wife waited around quite awhile listening to the radio and they never did. Oh well.)
BTW, for wedding music I entered to Bach's Wacht Auf, ruft uns die Stimme (found here) [a - D E F# - F# - E - G - F# - a - g - F# D E - g f# - C# D] and my bride entered to Clarke's "Prince of Denmark March (Trumpet Voluntary)" (found here) [D - - - - E ~ ~ ~ F# - - G F# - E - D - E - F# - E D E - a - a - a]. We had Bach's "Jesu Joy of Man's Desiring" as a eucharist piece.
How about the March from Saul.
