This is one of the ferries that crosses between New Zealand's two main islands. It's a trip that takes about three hours. Here we see it entering the harbour of New Zealand's capital city, Wellington. I took this photo while waiting to catch it to cross over.
And yes! regarding the melody first heard in the music - it does have a bar. However, it is often not a good idea to use it. Once you've left the safe confines of the harbour, the strait between the two islands is regarded as one of the roughest in the world! Today's music journey however, is a relatively smooth affair.
