Madonna Confirmed For GRAMMYs Performance
Saturday, 25 January 2014
Also added to the GRAMMYs lineup: Green Day's Billie Joe Armstrong and country star Miranda Lambert, who will perform a special tribute to Phil Everly, who passed away earlier this month; Trombone Shorty & Orleans Avenue; and rapper Juicy J, who will likely join Katy Perry onstage to perform their Top 5 hit 'Dark Horse.'
Madonna's last performance at the GRAMMYs came in 2006, when she performed her hit 'Hung Up' alongside Gorillaz. She has won seven GRAMMY Awards over the course of her illustrious career.
Previously announced GRAMMY performers include Daft Punk, with Nile Rodgers, Pharrell Williams and Stevie Wonder; Lorde; Sara Bareilles with Carole King; Macklemore & Ryan Lewis; Kendrick Lamar and Imagine Dragons; Taylor Swift; and many, many others. LL Cool J will return as host of the ceremony, which will take place at the Staples Center in Los Angeles.

Pop music is all about the here and now, the new and the current. Madonna is neither now. I am a huge fan of M and cannot stand Katy Perry; however, on this occasion, the seating arranagements were absolutely correct.

Madonna has been front row hundreds of times in her career. I'm sure she won't mind sitting behind Ms Perry as she is musically high profile at the moment with her current album....And Madonna and Katy are mates too.
