What is he playing on the guitar?

"Kumbya" or perhaps "Revolution", perhaps the theme song to the show "Mister Ed"? : )

[oblomov]

There was an old lady
who swallowed a horse
(she died, of course)

She swallowed the horse to catch the goat
She swallowed the goat to catch the dog
She swallowed the dog to catch the cat
She swallowed the cat to catch the bird
She swallowed the bird to catch the spider
That wriggled and jiggled and wiggled inside her
She swallowed the spider to catch the fly
But I dunno why she swallowed that fly
And now she died.

[F.J. Mitchell]

He's probably playing "Brother John" badly.
