Harry Nilsson's recording of John Lennon's song "Isolation" was released as a bonus track on the CD re-release of Aerial Pandemonium Ballet.
"Isolation" is a 1970 song appearing on John Lennon's first official solo album release, John Lennon/Plastic Ono Band. It ends side one of the album, and is the fifth track. In the Philippines, Apple Records released "Isolation" as the B-side to "Mother", the single off John Lennon/Plastic Ono Band, in contrast to most countries where the B-side was Yoko Ono's "Why". It was also released on an EP in Mexico along with "Mother", "Look at Me" and "My Mummy's Dead".
