“Baba O'Riley” by The Who was initially part of an idea (later thrown aside) of a follow up rock opera to Tommy: Lifehouse. Pete Townshend wrote it after his experience at Woodstock.

It did well as a single in Europe, but appeared only on the album in the US and the UK.

The name of the song is a combination of Meher Baba – an Indian guru who kept silent from 1935 until his death in 1969 and inspired Townshend spiritually, and Terry Riley – a musician and classical composer who also inspired him.

Mistakenly called sometimes “Teenage Wasteland” due to the repeating phrase.
