Tl;dr: Kash and Sevan cleared brambles and tree branches, cleared building waste, moved corrugated metal sheets, freed Mr R's ladder from the undergrowth and recovered tiles that had fallen off the roof

As the tiles lie
On a cold and grey Southall morn
A fierce little bramble grows with thorns
In the garden-o

And the homeowner cries
'Cause if there's one thing that he does need
It's to fix the roof and the ladder freed
In the garden-o

People, don't you understand
Mr R needs a helping hand
Or he'll grow to be an angry old man some day
Take a look at you and me
Are we too blind to see?
Do we simply turn our heads
And look the other way

Well, the world turns
And a GoodGym girl and boy with a runny nose
Cut down trees as the cold wind blows
In the garden-o

With the brambles spurned
So they start to bring indoors the light
And they learn how to tile
And they learn how to fight
In the garden-o

Then one day in expectation
The old man makes a change
He buys a lopper, the GoodGymers free his ladder
Tries to climb, but he don't get far
And he leaves the tiles

As friends gather round the hopeful old man
Standing on the ground with tiles in his hand
In the garden-o

And as friends climb to fix the tiles
On a cold and grey Southall morn
Another little bramble starts to grow
In the garden-o

But they've fixed the tiles
(In the garden-o)
(In the garden-o)
