"Did You Ever Have to Make Up Your Mind?" is a song written by John Sebastian and first released by his band The Lovin' Spoonful on their 1965 debut album Do You Believe in Magic. It was the second single released from the album and the most successful, reaching number 2 on the American Billboard charts for the week of June 11, 1966 (number 1 was "Paint It Black" by The Rolling Stones). It also reached number 2 in Canada. In New Zealand, the song charted at number 5.
The song has continued to be popular and has been included in many compilations of music of the period. In 1996, Denny's restaurants used the song for their $1.99 breakfasts.
In the 1999 film Dudley Do-Right, the song is given a big-band-style arrangement, and it starts with a swing dance battle between Snidely Whiplash and Dudley for Nell Fenwick, and evolves into a big production number. The lead vocals in this version are by Steve Tyrell.
The Christian parody band ApologetiX included a parody, "Did You Ever Ask Where Cain Got His Wife?", on their 2010 album Soundprooof.
