"They'll Need a Crane" is a song by American alternative rock duo They Might Be Giants, released as a single on February 10, 1989. In addition to vinyl and cassette releases, the single was released as a 3-inch CD. "They'll Need a Crane" was the first song the band performed on network television, in 1989 on Late Night with David Letterman.
The song's lyrics focus on the breakup of a dysfunctional relationship. According to AllMusic critic Stewart Mason, the song contrasts a "jaunty, uptempo melody" with "one of the bluntest depictions of divorce in popular music" about a couple (described as "Gal" and "Lad") whose relationship is crumbling. Mason notes that the song uses construction imagery to describe the relationship's degradation.
A music video for the single was directed by Adam Bernstein, a frequent collaborator of the band during their earlier years. It was filmed at the Bethesda Terrace in Central Park, New York City. The video primarily features the band playing with a group of elderly musicians, most notably jazz drummer Johnny Blowers who worked with Frank Sinatra during the 1940s.
