Eric Clapton and Florence Welch of Florence + The Machine will join The Rolling Stones onstage at tomorrow’s concert at London’s O2 Arena. As previously reported, The Rolling Stones got some help from former guitarist Mick Taylor and former bassist Bill Wyman, as well as Jeff Beck and Mary J. Blidge, at last Sunday’s O2 Arena show. Taylor and Wyman are also expected to make appearances at tomorrow night’s show. The concerts are part of the band’s “50 and Counting” 50th anniversary mini-tour, which also includes upcoming performances at Brooklyn’s Barclays Center on December 8 and Newark, NJ’s Prudential Center on December 13 and 15.
