 Before the 1998 release of Tony Fletcher 's Dear Boy : The Life of Keith Moon , Moon 's date of birth was presumed to be 23 August 1947 . This erroneous date appeared in several otherwise @-@ reliable sources , including the Townshend @-@ authorised biography Before I Get Old : The Story of The Who . The incorrect date had been supplied by Moon in interviews before it was corrected by Fletcher to 1946 .
