Thanks for your advice and patience. You'll see that in years long gone by I placed most of the words with Mudcat.   The problem is that the MIDI sample used doesn't match the Stewart Ross lyrics.   I can't read music so don't know which music is being used in the musical notation version.

If you cross reference the lyrics in the music you'll see that "O' I've wandered away.." should have read "though I've wandered away"
"Years long ago" should have been "years long gone by -" minor points I know but it does spoil the scanning.

The original structure as written in the sheet music and first recorded on record
was verse 1, chorus, verse 2, chorus, verse 3, chorus

Most recordings edit out the middle verse (2) as it's overall a bit long and monotonous in full.

I am only aware of two recordings where the full 3 verses were used - otherwise people prefer the shortened one.   Also my fathers tendency to use Scots abbreviations like O'er dates the middle verse.

Thanks
