John Mayer & Questlove Among Alicia Keys Guests At Surprise Show

One day after performing with Joe Russo’s Almost Dead at Brooklyn Bowl in New York City, Dead & Company guitarist John Mayer made his way to Times Square last night. Mayer was just one of many all-star guests to join Alicia Keys at a surprise concert in the Big Apple as Roots drummer Questlove, rappers Q-Tip, Jay Z and Nas also sat-in.

The concert came in support of Keys’ soon-to-be-released Here LP. Both John Mayer and Questlove contributed to Alicia’s own 2009 hit “If I Ain’t Got You.” Mayer and Keys threw in a portion of John’s “Gravity” within the lengthy “If I Ain’t Got You.” Watch video of the entire guest spot captured by Annette Appuliese:

Other memorable moments of Keys’ Times Square performance was her cover of John Lennon’s “Imagine” and Jay Z emerging for “Empire State Of Mind.”
