Morning

Islander guy walking through the tunnel with a guitar in one hand and milk crate in the other. Walks past an accordionist playing a Christmas carol.
Guitarist: "Do you mind if I play just up here?" Points down the tunnel.
Accordionist stops playing for a moment: "Oh yeah... Earshot, that's the main thing." Picks up the carol from where he left off.

Afternoon

On my way home the guitarist's still playing, and he's superb, great R'n'B voice and subtle strumming style.
