SOS versions have changed a lot from 1970s to 2016.
1985/86 versions were great, I only saw the broadcasted SOS of wembleys. It was not his best gigs.
Live aid versión was stronger
I like SOS 1985 american leg versions. San Antonio, niagara falls, texas
And the OES versions with the Pensa.
Before OES tour, Mandela's versión was flawless and the final solo a pearl
