"(And You Had a) Do-Wacka-Do" is a song by American country artist Roger Miller, released in 1964. The expression "do-wacka-do" is possibly a funny way of saying "do-like-I-do". Recorded in October 1964, the song was a lesser hit but it was one of Miller's most enduring lyric inventions.
The song expresses envy in a humorous way. The lyrics are written like a letter to a friend or possibly a former friend ("I hear tell you're doing well, good things have come to you ...") with whom the singer would like to trade places ("I wish I had your good luck charm, and you had a do-wacka-do, wacka-do, wacka-do, wacka-do, wacka-do").
