Slightly bothered by the OP's 'There are six videos with the same tune', bearing in mind the old jokes like 'they were playing the same tune all night. ' 'it all sounds the same anyway..', I watched two more of the six videos.

Nr 5 is The Gravel walks
Nr 6 is The Humours of Ballyloughlin, Ships are sailing Humours of Tulla, Skylark, Roaring Mary.
