Happy Birthday is a collaboration album by Pete Townshend, the guitarist for The Who and friends, including Ronnie Lane. It was pressed and released in 1970 by Universal Spiritual League.
The album was originally released in February 1970 (in commemoration of Meher Baba's birthday on 25 February) as the first in a series of tribute albums dedicated to Pete Townshend's spiritual mentor Meher Baba.
Only about 2,500 copies were pressed in the original 1970 issue.
The album was reissued in similar numbers in 1977.
