I have listened to the song and can only concur with what Mick has written above. I don't know what foom is - in the third verse it sounds more like food, but I could be mistaken. I think that the word damber may be damver, but again I could be wrong. I am sure it means dappled though, as it is in most other versions of the song. The persons to ask are Vic Legg or Vivienne Legg, both of whom will be familiar with the songs, as they are from the Renals family.
