Very good observation, as when Richard Lester directed the movie, he recorded it faster than normal for artistic reasons or something (I think it was like 25 or 26 fps?) and the original songs were recorded at that speed. However, to meet with TV standards, it is played at the normal 24 fps, so all the songs sound lower and slower
Now that's interesting!
