This bluesy groove has a killer riff that really gets me moving, and the lyrics remind me somewhat of the wandering cowboy lifestyle. The phrase “keep a stiff upper lip” means to remain cool and tenacious even when under pressure. Additionally, the expression “shoot from the hip” means to act quickly and impulsively, like a gunfighter in a shootout. As is common with AC/DC, it’s also obviously about fast and free sex. Ultimately, I really like the way this song comes together, and the guitar work is top-notch blues rock with a fine solo to boot!
