Water Water Everywhere

[Ryan]

Hi All,
Just wondering if anyone knows the chords to Tommy Steele's 'Water Water'? I play G bar chord, Open C7 Shape from fret 3 (which i think makes it some sort of D7), C bar chord and D bar chord.
Don't know if this is correct, don't think it probably is, sounds to me that it could be some sort of jazz chords which i do not know.
Cheers
Ryan
