I remember the Schaefer jingle. How about Miller and Bud:
(Sung sort of sleazily, like you might sing "Hey Big Spender")
"If you've got the time
We've got the beer
Miller beer
Miller tastes too good to hurry through
When it's time to relax
Miller stands clear
Beer after beer
If you've got the time
We've got the beer!"
(Sung heartily)
"When you say Bud,
You've said a LOT of things noBOdy else can say
When you say Bud,
You've said you CARE enough to Only want the KING of beers
When you say Bud-wei-ser,
You've said it all"
