The TV advert says that the “Searching For Sugar Man” soundtrack “includes 3 previously unreleased songs” but this is not true.
“Street Boy”, “Can’t Get Away” and “I’ll Slip Away”, recorded in 1972/73, were first released on the Australian “At His Best” album. They are also included as bonus tracks on the 2009 US release of “Coming From Reality” (which is known as “After The Fact” to South Africans).
The “Searching For Sugar Man” soundtrack album also leaves off “Rich Folks Hoax” which contains the classic opening line “the moon is hanging in the purple sky”. Sugar Man – The Best Of Rodriguez is a better collection for rounding up his best and most popular songs.
