MESSING ABOUT ON THE RIVER

(Anthony)

(Performed by Josh Macrae)

When the weather is fine
Then you know it's a sign
For messing about on the river

If you take my advice
There's nothing so nice
As messing about on the river

There are longboats and short boats and all sorts of craft
And cruisers and keelboats and some with no draught

So take off your coat
And hop in a boat
Go messing about on the river

There are boats made from kits
That reach you in bits
For messing about on the river

Or you might like to scull
In a glass-fibre hull
Just messing about on the river

There are tillers and rudders and anchors and cleats
And ropes that are sometimes referred to as sheets

With the wind in your face
There's no finer place
Than messing about on the river

[Up a tone]

There are skippers and mates
And rowing club eights
Just messing about on the river

There are pontoons and yachts
And all sorts of knots
For messing about on the river

With inboards and outboards and dinghies you sail
The first thing you learn is the right way to bale

In a one-seat canoe
You're the skipper and crew
Just messing about on the river

[Up another tone]

There are bridges and locks
And moorings and docks
When messing about on the river

There's a whirlpool and weir
That you mustn't go near
When messing about on the river

There are backwater places all hidden from view
And quaint little islands just waiting for you

So I'll leave you right now
To cast off your bow
To go messing about on the river
