Fishy Sleeps

Please help - want to find out who wrote this song so I can buy it as an MP3.

The chorus goes:

Fishy sleeps, fishy sleeps, fishy sleeps, feed the fish.

The start of the song has the singer talking saying:

When John Richard first showed me this song it did not thrill me, but the title sort of got to me and we worked together on a few changes and the more I got into the song the more it grew on me, listen to this, this is a stange idea.

Then the start goes:

Lay your head down little one,
Your eyes are sleepy and the sun has gone,
to send the fish a lulaby.

The song is from the late 60's early seventees and the singer sounds american but may be wrong.

Please help!

Thanks

Leigh
