Here's a video someone (I don't know who) made at an IHS event. Note that the video doesn't include the entire song, which goes like this:

We're doing battle with statists
Across the USA,
'Cause everybody's reading Hayek,
The man from Austri-ay --
In spontaneous order
We let the market play,
With the writer Fred Hayek,
H-A-Y-E-K.

We use the signals of prices
And then we'll be O.K.,
'Cause no one knows what's efficient
Unless they have to pay;
If we replace that with planning
Like once in Russ-i-ay, [pronounced "Rush-Eye-Ay"]
We'll take the road to serfdom --
Serfdom USA.

[Backup singers should at this point start singing, "Serfdom, serfdom USA, Friedrich H-A-Y-E-K."]

We still have government bureaus,
Just like the FDA, [replace with three-letter agency of your choice ending in A]
But the welfare state mindset
Will soon become passe.
Ayn Rand said he was evil,
Which makes him A-O.K. --
Friedrich August von Hayek, H-A-Y-E-K.
