Controversial, but the real, cover of the self-titled Blind Faith album (1969)
July 1969? -- no, not my 13th birthday, but thanks.
Answer: release the album Blind Faith. The tracks Can't Find My Way Home (live filmed version here) and Presence Of The Lord (audio only album version here) will live forever.
Can I get an "Amen"?
Most folks pick the first moon landing as the most important event of July 1969. Very important, I was there watching the rocket take off on the 16th, but without the two songs noted above, my life would be empty and confusing. Now it is neither.
