"Moby Dick" is an instrumental tune and drum solo by English rock band Led Zeppelin, featured on their 1969 album Led Zeppelin II. Named after the whale in the novel Moby-Dick by Herman Melville, it was also known by the alternate titles "Pat's Delight" (early 1968–1969 version with completely different guitar riff) and "Over the Top" (with "Out on the Tiles" intro section and original closing reprise) during various points of the band's career.
Bonham's drum solo was often played at Led Zeppelin concerts from the first North American tour in November 1968, being his solo performance showcase on concert tours through 1977. Over this period it went through three different name changes. During their early 1968–1969 tours it was known as "Pat's Delight" (a reference to Bonham's wife), from 1969–1975 it was "Moby Dick" and during Led Zeppelin's 1977 North American Tour it was "Over the Top" as the solo began with the opening riff to "Out on the Tiles" before segueing into a lengthy drum solo (in the same time ending with a "Moby Dick" riff).
When played live, Bonham's drum solo would last as little as 6 minutes or, more frequently, as long as 30 minutes, while the rest of the band would leave the stage after having played the introduction. During the performance Bonham would often set aside or throw his drumsticks into the audience and then continue the solo with his hands (sometimes drawing blood as a result).
