Initially, the song "Running Back" was chosen to be a single ahead of "The Boys Are Back in Town", the latter being seen as possibly too aggressive for some radio stations to play. Lynott and producer John Alcock decided to employ session musicians to add more commercial elements to some of the tracks and try to produce a hit single, so Tim Hinkley was brought in to add keyboard parts to "Running Back". Robertson was against the idea, as he liked the song as it had originally been arranged, in a blues format with his own additions of piano and bottleneck guitar. He later said, "I took enormous offence to changes. I couldn't understand why they'd pay this guy a fortune just for playing what he did. Listen to it and tell me it's not bollocks." Robertson did not play on the finished version of the song and Hinkley is not credited on the album sleeve. Lynott said at the time that "Running Back" was "very much influenced by Van Morrison. I really like that song." Hinkley later recalled, "Robbo and Scott were not keen on it at all but they were overruled." Thirty-five years later, Robertson recorded his own versions of the song on his 2011 album "Diamonds and Dirt".
