For completeness and to round it up so to speak, the two missing answers to mine were -

OG 1 - when a man gets married his race is run - Free and Easy (Trad) learnt many years ago off Tom Gilfellon's first LP

OG 3 one son drives a long limousine - Butch Hancock's Own and Own which is my favourite use/play on words song

All the best
