The only song which appears in the original songbook is Flower of Scotland.

I wonder if that's a mistake. The original (unless there's another one) is a slim slick paper book with only 16 songs. There's no date on it but Roy gave me a copy about 1972 (It likely cost him 6p.) Some good songs in it & in fact, I just sang "Banks of Newfoundland" to mark St. Pat's Day.
