Something for Thursday

So, time to get back to our on-again, off-again song challenge! If my reckoning is correct, we're up to A Song I'd Sing With Someone In A Karaoke Duet. Well, I'm honestly not likely to ever sing karaoke in any foreseeable future, but if I did...well, this category vexed me a bit which is why I'm actually so late today with this post. Only one song really leaps to mind for me as one that might get me up to the microphone (and a bit of alcohol infused into my system would also be necessary), and it's this one, from Grease. Am I sure? Yes I'm sure! Yes I'm sure down deep inside!
