I think the Original chords are C5 , G5 , C5 , F5 , C5 but I prefer G5 , D5 , G5 , C5 , G5

            G5                          D5
Down by the bay, where the watermelons grow

                           G5
Back to my home, I dare not go

         C5                   G5
For if I do, my mother would say,

(verse spoken-no chords)
"Have you ever seen a bear combing his hair?"

D5          G5
Down by the bay.
