This day in music history.

April 22, 1978, Paul Schaffer acting as Don Kirschner introduced John Belushi and Dan Aykroyd as The Blues Brothers for the first time on "Saturday Night Live." The boys open the show with "Hey Bartender".
Hey Bartender by Floyd Dixon
I went balling the other night
I started drinking and got real tight
I blew each and all my friends
I felt so good I had to blow it again
I said hey bartender
Hey man, looka here
A draw one, draw two, draw three, four glasses of beer
Well I saw a chick sitting on the end
I said baby can’t we be friends
You’re looking sweet as you can be
Well come on down and drink with me
I said hey bartender
Hey man looka here
Draw one, draw two, draw three, four glasses of beer
Well we was having so much fun
I didn’t know it was half past one
I turned around to have one more
I looked at the clock and it was half past four
Hey bartender
Hey man look a here
A draw one, draw two, draw three, four glasses of beer
Well jukebox girl is everything
All the cats began to sing
I heard somebody called and said
Last round for alcohol
I said hey bartender
Hey bartender
Hey bartender
Hey bartender
Draw one, two, three, four glasses of beer
