What hit song plays on the radio alarm clock in the movie "Groundhog Day"?

"Groundhog Day" is a 1993 American fantasy-comedy film directed by Harold Ramis, starring Bill Murray, Andie MacDowell, and Chris Elliott. It was written by Ramis and Danny Rubin, based on a story by Rubin. Murray plays Phil Connors, an arrogant Pittsburgh TV weatherman who, during an assignment covering the annual Groundhog Day event in Punxsutawney, Pennsylvania, finds himself caught in a time loop, repeating the same day again and again. After indulging in hedonism and committing suicide numerous times, he begins to re-examine his life and priorities.

On February 2, Phil awakens at his Punxsutawney bed and breakfast to Sonny & Cher's "I Got You Babe" on the clock radio and the declaration, "It's Groundhog Day!" He tapes a half-hearted report on Punxsutawney Phil and the town's festivities. Rita wants to stay and cover some of the other events, but Phil wants to return to Pittsburgh immediately. The blizzard—the one that Phil predicted would miss the area—resolves the issue by blanketing the region in snow, stranding them in Punxsutawney. Phil shuns the celebrations and retires to bed early.

This repeats for several days until finally on one loop, Phil decides to tell the woman he is interested in that he has feelings for her. Phil wakes to "I Got You Babe" again, but finds Rita is still in bed with him, and Punxsutawney covered in a fresh blanket of snow; it is February 3 and he has been able to escape the time loop.
