I am seriously looking for your input on this; I assure you it is not a trick question, but what I think to be a very simple and straightforward one. That said, I am not doing this as a multiple-choice poll, but open-ended, for reasons which I will reveal at a later date. Please do leave your answer in the comments, even if others have already answered (and please do your best not to be influenced by earlier answers, whether they agree or disagree with yours). And despite this being the internet, I am asking for your honest first answer (even if it is “I don’t know”). Please do not google, bing, or otherwise search–I’m not looking for their answer, I’m looking for yours.
The question is: Who sang “The Rainbow Connection”?
