The sky is pink, the trees look warm and brown

The sky is pink, the trees look warm and brown
The heat has come to London for a stay
The kitchen feels so humid, I might drown
The sky is pink, the trees look warm and brown
Unusual shades on this side of the town
But lovely pink for a kind wedding gown
If you have a credit card to pay
The sky is pink, the trees look darker brown
The heat has come to London in late May
