This tune is often called Captain Pugwash because it was used as the theme tune for a very popular children's television programme. The original was slightly different; the chromatic run in played in the B part nowadays is a more recent addition, possibly dating from the TV theme which was played by accordionist Tom Edmundson in 1957. He in turn learned the tune from Jinny Shand, so it's possible that the version played now had a strong Scottish connection, but it is by no means clear.
