Jeff St. John from Joint Effort (1970) to So Far, So Good (1978)

It must have been something to see this guy live, because as it says on the discogs brief bio:

Australian musician and singer born with spina bifida and spent much of his life in a wheelchair. Born 22 April 1946, Newtown, New South Wales; died 6 March 2018 at his home in Perth, Western Australia. Also known as Jeffrey St. John.

I wonder, and am amazed, at how much confidence and strength you'd have to have to overcome a disability like that and 'make it' in the rock 'n' roll world.

From the 1971, Cloud Nine:

On the 1978 album the track called Starbrite is one of those songs I've mentioned before that seems like it should have been a number one hit on radio back in the day, it has everything you'd need for it, like the powerful hook, the strong singing, the diatonic classic-70s pop chord progression:

Just like that song called Headin' in the Right Direction which, of course, really was a hit in Australia at least back then, for the wonderful Renee Geyer.
