MADIGAN'S LOCK
(Pete St. John)

Hey ho and up she rises O
at Madigan's Lock.

CHORUS:
At Madigan's Lock there's a rare old stock
and they drink a magical brew
made of dreams and air brain schemes
that will make no sense to you.
O the pub's a pub in any port
(______________) never dock. [?]
By a lost canal you never shall
see the likes of Madigan's Lock.

If dreams were wishes and wishes were fishes
we'd all go catch our share
but dreamers seldom live their dreams
cause dreams are hard to share
and the daily strain upon the brain
can be a terrible shock
but it fades away at the end of day
with a pint at Madigan's Lock.

chorus

If you can dream then join the team
we'll all just sail away
and by and large we'll toast our barge
and not mind what they say.
She's built of timber, made of hope,
with a dream in every seam.
We'll slip the dock for Madigan's Lock,
we're sailing on a dream.

Hey ho and up she rises O
at Madigan's Lock.

chorus
