Just a glass of rum.

Three men are in a music store, with the man on the right playing a guitar and singing loudly with his head tilted back, while the man on the left, holding a guitar, smiles and watches him, and a third man in the background laughs. The man on the right continues to sing with exaggerated expressions, the man on the left maintains a smile and looks at him, and the man in the back keeps laughing, all within a store setting with Yamaha branding visible.
