Mary was married with children,had the perfect suburban life,till her husband came clean with the help of Jim Beam confessed all his sins one night. Said he'd fallen in love with a barmaid said she made him feel reckless and young and when he was through what else could she do she just let that pony run. (Chorus)Cuz ya do what ya gotta do and ya know what ya know and ya hang on till ya can't hang on then ya learn to let go and ya get what you need sometimes and when it's all said and done you do what ya gotta do then you let that pony run. Oh oh oh ho. Now Mary moved to West Virginia after the shock wore off.She got a divorce and a chestnut horse and a barn with an old hayloft. Sometimes she rides down by the river said it makes her feel reckless and young .She just closes her eyes and she holds on tight then she lets that pony run. Repeat Chorus ----Let that pony run.
