The version Christy Moore recorded on "Prosperous" included verses 2 & 3 of Robbie's with minor changes. I'll need to dig out and listen to confirm the details of the changes.
The five verse version is the "standard" one regularly bawled out in pubs. I don't remember who recorded it first - but am fairly confident it was before Christy Moore. I'll check.
On a minor point in Frank's copy of Robbie's version, the name in verse 5 is normally spelled "Moylan"
p.s. On Wolfgang's point regarding the tune: O Cillin's book was published in 1976 - at which stage the short version was very well known under the title "Spancel Hill". I suspect that's all he meant.
