This is the story of an old man, who is walking in the streets of a city in England, in the evening. He goes to see whores… he’s got Parkinson’s disease. He’s got problems in his mind so he goes in a pub to drink. He takes the train, meets acquaintances there.
At the end of the evening, he goes back home…
It’s a sad story but the rhythm of the song is happy / joyful.
