Such an ah-MAZING mash-up! We can't believe this never saw the light of day!
Although it didn't make the final set-list, Madonna apparently recorded a new version of her classic Burning Up, cut together with Impressive Instant from the more recent Music, for her 2008 Sticky & Sweet tour!
Check it out, along with the backdrop (above)!
So, SO cool! Inspired decision, really!
We would have LOVED to see this live!
Perhaps she can re-work it and use it on her next tour, though!
