WKRP in Cincinnati was one of the best television shows of the 70s, if not the entire history of television. Below is the opening for the show, without the classic radio dial switching, (looking for radio station WKRP). That clip used to be on YouTube but I guess the YouTube-Internet police got to it.
In any case, sit back and enjoy. Sing along if you must. You will find you cannot help but sing along.
"As God is my witness, I thought turkeys could fly." - Arthur 'Big Guy' Carlson as played by Gordon Jump on "WKRP in Cincinnati"
