Side two begins modestly with "Silver Train," a rock & roll song with a pre-rock flavor. The Stones' approach is like their treatment of "Stop Breaking Down," one of Exile's sleepers: lots of whiny slide guitar and harp. They also emphasize, with their ragged ensemble shouts, the song's appealing chorus. "Train" is the best of the album's secondary songs.
Johnny Winter had heard a demo of the tune and recorded a cover of it for his album (Source ?), Still Alive and Well in 1973 (Columbia Records). Song written for Johnny Winter by Mick Jagger & Keith Richards. His album's version was released even before Goats Head Soup.The Black Crowes have also covered the song live. Silver Train also appears on the Carla Olson / Mick Taylor "Too Hot For Snakes" album first released in 1991 and reissued autumn of 2012.
The song was played 4 times in 1973 and wasn't played again until 2014 in Tokyo on the 14 On Fire tour with Mick Taylor, who played on it originally, as a special guest.
