However, with one of those - "Hallelujah Sunshine" - we can at least listen to a version which half of Rabbitt also performed on, and it appears on Margaret Singana's 1977 album Tribal Fence.
You probably want to stop me at this point to note: "But those songs have two different titles!" This is true, but I believe that Rabbitt's version may have been retitled thanks to government censorship. And if it sounds like too much of a stretch for credulity's sake, I will state that two songs which contain hallelujah as the first word of a two-word title both credited as being written by someone with the surname of Campbell? What are the odds?!
Continuing with my assertion, the song is actually titled "Hallelujah Freedom" - written and originally performed by Junior Campbell, a Scottish singer/songwriter who had a hit in the UK and Europe with the song in 1972. Rabbitt's version was recorded and released in 1973. Viewing the production credit, I'd say it's a fair assumption that Mutt Lange produced the session.
Margaret's version was recorded for Tribal Fence featuring Trevor on guitar, bass, keyboards and backing vocals, Neil Cloud on drums, with additional guitar and percussion by Julian Laxton and additional backing vocals by Rene Veldsman with Avril and Miriam Stockley. Trevor arranged and co-produced the track.
And why would the South African government censor such a song? In 1973 it was standard practice for anything which could be considered remotely objectionable, just as they censored Rabbitt's first version of "Locomotive Breath." Specifically, when you consider the song's lyrics - which portray an oppressive situation - well, I would say it's fairly obvious that they would seek to suppress anything which could possibly be construed as political.
