MacCrimmon in the Cave of Gold.
MacCrimmon went into the Cave of Gold and played the pipe tune 'Cha Till MacCruimein' [MacCrimmon Will Never Return]. The contributor recites some of the words to the tune. MacCrimmon never returned from the cave. Before he set off, the fairy woman told him that, if his wife set the table as usual he would return. His wife didn't put butter on the table.
