Which Beatles song by McCartney was inspired by the Who's 'I Can See for Miles'?

The McCartney-written Beatles song inspired by the Who’s “I Can See for Miles” is Helter Skelter.

Paul McCartney wrote Helter Skelter after reading Pete Townshend describe the Who’s 1967 single as the loudest, rawest and dirtiest song the band had made. McCartney treated the comment as a challenge and set out to create an even more extreme recording. The result became one of the Beatles’ heaviest and most chaotic performances.

The song was recorded in several sessions during July and September 1968 and released on The Beatles, commonly called the White Album, on 22 November 1968. McCartney handled the lead vocal, while the other Beatles contributed drums, bass, guitars and studio noise. The stereo version is especially notable for its extended, turbulent ending.

Helter Skelter is often described as an early influence on heavy metal, although it also draws on hard rock, blues-rock and the Beatles’ taste for experimentation. The title refers to a British fairground slide, not originally to violence or crime. Its later association with Charles Manson came from his interpretation of the song, not from McCartney’s stated inspiration.
