G C G Once upon a time there was an engineer, G A7 D7 who drove a locomotive both far and near, G C Accompanied by a monkey who would sit on a stool, G A7 D7 G watching everything the engineer would pull. G C G One day the engineer wanted a bite to eat, G A7 D7 He left the monkey sitting in the driver's seat, G C The monkey pulled the throttle the locomotive jumped the gun, G A7 D7 G and at 90 miles an hour down the main line run. Chorus: G C G The big locomotive is right on time, G A7 D7 the big locomotive coming down the line, G C The big locomotive number 99, G A7 D7 G left the engineer with a worried mind.
