But when they added harmonica breaks and sped things up to a rollicking footstomping pace, BRMC delivered two of the best songs of the night: Beat the Devil's Tattoo's gospel-inspired howl, and Ain't No Easy Way, which sounded like the soundtrack to the best Clint Eastwood Western ever.
You half expected him to kick the Powerstation's door down brandishing spurs and a couple of six shooters.
Sure, after 90-minutes of thrillingly bleak, chest-thumping rock 'n' roll infused with jackhammer strobe lights, an encore that included two low-fi acoustic songs - Complicated Situation and Shuffle Your Feet performed sea shanty-style around a single microphone - might have raised a few eyebrows.
Hayes and Been, who shared singing duties throughout the night, were so subdued they could barely be heard over the roar of the crowd, and the chorus of shushing that echoed around the venue made things even worse.
But they made up for it by signing off with the grungy bottom-end sludge of Sell It, and as the final searing riff rang around the Powerstation, a room full of lifetime BRMC members left sweaty, smiling and with ears which will be ringing for a long, long time.
