The first seasons was initially sung by Todd Griffin, but beginning with the second season, the song was performed by the band Cheap Trick, whose version is referred to as "That '70s Song (In the Street)."
The lyrics are as follows:
Hanging out. Down the street.
The same old thing, we did last week!
Not a thing to do, but talk to you!
We're all alright! We're all alright!
Hello Wisconsin!
