What movie/tv show is this? I CAN'T REMEMBER.?

There's some movie or tv episode I used to watch often when I was a kid, but I can't remember what it was. I can't remember if it was animated or live action. The plot is that there is some wedding about to happen, and there's a little girl who's too small to be a part of the wedding, so she's sad. Her sibling or cousin or something is the ring bearer, but he trips while walking down the aisle and the ring goes flying, and it falls into one of the tubes of the organ, and gets lost down there. The little girl is the only one small enough to fit inside the organ, so she gets in there and finds it and saves the wedding! DOES ANYBODY REMEMBER THIS?!
