Everywhere I go the shout is "Swinging"

Seems to me that swing is king

And if that is so

I would like to know

What is this thing called swing

When I hear a tune try to sing it

In a crooning voice like Bing

But the band gets hot

And I'm on the spot

What is this thing called swing

With great persistence

I've sought assistance

From homes and filo fans

They told me in advance

They too proclaim it

But simply can't explain it

If someone knows

I wish they'd spring it

So that I can solve this thing

For goodness sake

Give a guy a break

What is this thing called swing
