What is the name of the Budweiser theme song?

I'm sure there have been more than one, but the one that comes to mind (the one with the ants) is 'Get Down Tonight' by KC and the Sunshine Band.

The budweisersong.

'...so I decided to look there for the words to the song. And I found them:'

'Here comes the king, here comes beer number one (Here comes the king)
Budweiser Beer -- the king is second to none...
The king is coming, just hear the call,
When you say Bud, you've said it all,
When you say Bud, you've said it all
Ya da da da da da da da da da da....'

"Here Comes the King" written by Steve Naren


Here comes the King, here comes the Big Number One
Budweiser Beer is Beer that's second to none
The King is calling, so loud and clear
There's only one Budweiser Beer
There's only one Budweiser Beer

Here Comes the King is a well-known advertising jingle written for Budweiser, the flagship brand of the Anheuser-Busch brewery, and whose slogan is, "The King of Beers". First played in circa 1976, it is often played as a theme song for the Budweiser Clydesdale horses pulling the Budweiser beer wagon. It was written, words and music, by Steve Karmen in 1970.
