To get permission to use this song in the movie School Of Rock
, the star of the movie, Jack Black, videotaped himself singing in front of a huge crowd of people, begging Led Zeppelin to let them use the song in the movie. They succeeded, and the song was featured in a scene where Black sings along to the tune when it comes on the radio in his van, which he is using to transport his students.
"It may seem corny, but it worked," Jack Black said on the DVD. "The moral of the story is, Don't be too proud to beg."
