It on RU-vid . He is singing it at the 1993 March on Washington. Seeing him do it is my number one RU-vid tearjerker. He died that same year. I used to hear him sing iit st the beginning of every AIDSWALK in the mid to late eighties. It is also in an album by his group The Flirtations called Purple Heart.
This Video is amazing thanks so much for uploading this being in the UK I never got the chance to see The Boy From OZ now I do. Do you have Tenterfield Saddler?
