Willie, bring your little drum Robin bring your flute and come, we'll be joyous as you play Tooralooraloo, pat-a-pat-a-pan. We'll be joyous as you play on a Merry Christmas day! When the men of olden days gave the King of Kings their praise, they had pipes on which to play Tooralooraloo, pat-a-pat-a-pan. They had drums on which to play, full of joy on Christmas Day. God and man this day become, join us one with flute and drum, let the happy tune play on Tooralooraloo, pat-a-pat-a-pan. Flute and drum together play as they sing on Christmas day.
