The song that popped into my mind this morning

I'd be tender
I'd be gentle
An awful sentimental
Regarding loving art
I'd be friends with the sparrows
And the boy who shoots the arrows
If I only had a heart

Of course you recognised the tin man's theme from the Wizard of Oz
And to make it worse, when I switch on the radio I get Eleanor Rigby from the Beatles, which goes:
I look at all the lonely people

Which obviously reminds me of:
To live a better life
I need my love to be here
...

The bottom line being: oh, you just figure it out.
