HONK is certainly a cute show with some very sweet songs in its score, but it is definitely surprising that it was able to overtake The Lion King and also the more prestigious work of Spend, Spend, Spend which got most of the precursor attention.
I almost view this as a pre-Avenue Q/Wicked type scenario where the smaller show over took the big epic. I recall seeing a video of the moment Stiles & Drewe won for it and one of them said with much surprise something to the effect of "I guess the voters couldn't get tickets to see The Lion King".
Plus, that production is such a mystery because I cannot find a single video/audio recording of it and the most I can find are few pictures.
