A sunglasses-clad Queen of Pop and an equally vacation-style Jimmy Fallon teamed up for an acapella sing-a-long on Thursday, April 9, joining his house band The Roots for a classic edition of his famous Classroom Instruments bit.
The 56-year-singer grabbed her cowbell while Fallon took a wood block and the famous duo proceeded to perform a perfect rendition of the hit Madonna song on The Tonight Show, accompanied only by a xylophone, a banana shaker and a few other classroom favorites.
Fallon joined his band The Roots in donning a bright and colorful Hawaiian shirt, while Madge remained characteristically cool in an all-black outfit accessorized with gold chains (and a gold whistle, which she happily blew along with the tune).Despite the performance being an all-seated affair, the "Material Girl" couldn't resist a bit of a boogie, and mid-way through the performance pushed her cowbell aside to do some seated-dancing with her arms.
