Just ordered, And I haven't even got a Wii U.

Just ordered, thanks!

Much heat, thanks OP. Throw in a £10.99 Amiibo, Mario Classic Modern Colours for example is this price along with many others, and your just a few pennies over the £20 free delivery price.

Hi can this be played on a normal Wii console too ?

Wow nice price gotta be done thanks.

Worth it for the Mics but Nintendo's own Karaoke software from the on-line store is much better.

Thank you. A great pity. At that price could have been an extra little something for my budding rockstar :smiley: ...certainly has given me an idea to seek out a compatible one....

Ordered, thanks!

Can get plenty of singing games cheap for under a couple of quid this days on wii - just would need the microphones which can be had in bundles (with games such as boogie etc) or seperately
