Can't help personally,but our residence cyber-sleuth, Joe "three minute" Offer is a lighthouse fan so he may help.
For the other queries it's better to put in separate threads :"Adge Cutler" , "Singing Postman" to attract attention.
I have one Wurzels LP but has mostly trad. songs, only a couple of originals. If there is a specific song, better to put it in the heading. When I'm back from leave and not too busy I can write out & then post AC's lyrics off the Wurzel's record if no-one else beats me to it.
Refresh the thread in mid Oct if you've had no better response. I thought "Drink up thee Cider" was already in the DT, but can't see it, try a thread search, I'm sure someone has posted the lyrics in the last year. Roger
