...incredibly annoying “It’s a Small World” song.”
When my daughter was three we took her to Disney in Calif. She loved that ride and had memorized the song and was able to sign it out after only the first ride - singing it millions of times over the years, as a matter of fact. The next time we went to Disney was 10 years ago when she was 39 and she and I took her the grandson. She sang it out loudly during the ride. She was killed in an auto accident shortly after that. Wish I had recorded her singing it. While it may be annoying to you, hearing it does trigger memories which are precious to me.
I am truly sorry for your loss. :(
