im rehearsing for the nottingham scout gang show at the minute.
we sing:

we're riding along on the crest of the wave
And the sun is in the sky
All of our eyes on the distant horizon
Look out for passers by
We'll do the hailing
While all the ships around are sailing
We're riding along on the crest of the wave
And the world is ours

Sailing the seas is
Great when the breezes
Seem to just blow us along
And though before we
Land there'll be stormy
Weather we'll face it with song
High through the billows we'll go crashing through
We are the gang show crew

then the chorus again but the actions i can remember are on the lines
sun is in the sky (tapping hand on head. up down out!)
