So lets talk Let's Sing 2016. This game was a super late release Wii title which had limited production numbers. About a month after the games release, it was recalled across the country.

The general thought was that the microphone that was included was crappy. The flyer says the disk may not load.
The game became pretty hard to find due to the recall.
A few days ago I was snooping around amazon.ca and found this review:

Say what! Nudity in a Wii game. Nudity in a game that got recalled. hmm... interesting.
After some investigation:

Not only that, but this uncensored music video, seems to be the only uncensored version in existence. I couldn't find a single copy of this version of the video on youtube or any other streaming site. Even videos marked "uncensored" showed no nudity. Whoops. I guess we have our first and only Wii game with Nudity and a good reason for a recall.
