A man is beautiful

It's perhaps a minor issue, so give it perhaps a minor thought. What's wrong with this poem:

A man is beautiful

but

you have to swing

and swing and swing

and swing like

a handkerchief in the

wind

Well, consider this one:

A woman is beautiful

but

you have to swing

and swing and swing

and swing like

a handkerchief in the

wind

That better, right? Well, it's also from Jack Kerouac, the last one. But that's not the only thing. Let's think about this some more.
