Here are the words for the full song: www.rampantscotland.com/songs/blsongs_herring.htm We once stayed in a cottage neat Eilean Donan castle for a holiday. One morning someone knocked on the door and said she had some fresh herring, just caught, so I bought some. I fried them quickly, but really you could almost have eaten them raw. The bones were so soft they melted.
Sae smooth his speech. Sae true his hert. His breath's like caller air His very fit has music in't when he comes up the stair.
This is from a song called There's Nae Luck Aboot the Hoose in which the singer welcomes sight of her husband's boat coming back to port for the first time in weeks. The singer says there is no luck or happiness in her home when her husband is away. Yes, caller is fresh (and fit is foot).
