Hiya, I wondered if it was a synthesiser making some sort of accordian sounds?

I didn't know about Sailing Home until someone used the music to accompany a video of a ship going under a bridge and bashing the superstructure off. It was Gary who pointed me to the tune.

One Way Wind was The Cats biggest hit.

From what I've read it seems that Piet Veerman used backing tapes when singing live which was why there were no signs of any musicians in videos.

Just found this, it's a synthesiser:-
