some sources say Earl "Wya" Lindo wrote half the song and later on Bob added some lines.
when live performed, Bob began alone with his acoustic guitar, sang the second verse a-cappella, and was then subsequently joined by Carlton on drums, Seeco on percussion, and finally the rest of the band which played an extent version of the bridge.
the SBD recording from the last show in Pittsburgh has been released on the Songs Of Freedom compilation (see 1980-09-23 for more details). However, the audience screaming and Bob's thank-you at the end of the song actually comes after "Is This Love?" of the same show and has been mixed for the released track.
the band version was performed at least once live on stage, in Dijon (see 1980-06-04); the first part of the performance was Marley with guitar and the band subsequently joining for the bridge as usual; then Marley took again the first verse with the band playing, which made this performance unique.
