I misread the title at first – I thought it said "Run On The Beach" – a good, healthy exercise.
Then, when I found the reference to imbibing rum, it suddenly clicked – it's a drinking song – and it's not the kind of exercise one can do while running because you spill too much.
There's a lot to like here, Mario. From the well-chosen sounds to the cleverly deceptive chord progression that tricked me a regular intervals, moving in totally different directions than those I had anticipated. A very interesting experience. Well done.
