Dolly Parton is one of the world's great superstars, feted for her figure as much as for her music. Platinum Blonde goes inside her world to discover the woman under the wigs as she returned to the concert stage in the UK in 2002 after an absence of 20 years. Born into grinding poverty in rural Tennessee, Dolly has risen to the top of her tree in music, films and as a businesswoman who owns her own theme park. Friends, family and colleagues - including Lily Tomlin, Kenny Rogers, Billy Connolly, Dabney Coleman and Alison Krauss - help tell her story, along with the full and frank views of Dolly herself. With cameo appearances from Sinead O'Connor, Norah Jones, Jonathan Ross and Terry Wogan.
