A change to the rock side of sounds.
Bill Haley's;

One, two, three o'clock, four o'clock rock
Five, six, seven o'clock, eight o'clock rock
Nine, ten, eleven o'clock, twelve o'clock rock
We're gonna rock around the clock tonight
Put your glad rags on and join me hon'
We'll have some fun when the clock strikes one
We're gonna rock around the clock tonight
We're gonna rock, rock, rock, 'till broad daylight
We're gonna rock, gonna rock around the clock tonight
When the clock strikes two, three and four
If the band slows down we'll yell for more
We're gonna rock around the clock tonight
We're gonna rock, rock, rock, 'till broad daylight
We're gonna rock, gonna rock around the clock tonight
When the chimes ring five, six, and seven
We'll be right in seventh heaven
We're gonna rock around the clock tonight
We're gonna rock, rock, rock, 'till broad daylight
We're gonna rock, gonna rock around the clock tonight
When it's eight, nine, ten, eleven too
I'll be goin' strong and so will you
We're gonna rock around the clock tonight
We're gonna rock, rock, rock, 'till broad daylight
We're gonna rock, gonna rock around the clock tonight
When the clock strikes twelve we'll cool off then
Start rockin' 'round the clock again
We're gonna rock around the clock tonight
We're gonna rock, rock, rock, 'till broad daylight
We're gonna rock, gonna rock around the clock
