Legendary singer Aretha Franklin has been advised by her doctor to cancel a number of concerts. The 74-year-old singer has axed an upcoming gig in Virginia this month, along with a performance at Tony Bennett Celebrates 90 and a solo show at New York City's Radio City Music Hall in September. Franklin is currently busy working on her upcoming biopic and is delighted with the person who will portray her in the as-yet untitled project.
