Because the husband loves it, and I love him.

(Also, not for nothing, but the video’s kind of adorable).

Shirley,
your sexual politics have left me all of a muddle
Shirley,
we are joined in the ideological cuddle

I’m celebrating my love for you
With a pint of beer and a new tattoo
And if you haven’t noticed yet
I’m more impressionable when my cement is wet

Politics and pregnancy
Are debated as we empty our glasses
And how I love those evening classes

Shirley,
you really know how to make a young man angry
Shirley,
can we get through the night without mentioning family
