No one knows why she waited so long to embark on a world tour. Perhaps she felt it wasn't a necessity because she was doing the triple threat thing and a tour just wasn't important back then. I'm glad she finally got round to it in the end. Her HBO tour documentary 'Dance Again' was insightful. Too much narrative and not enough performances was my only issue but it was still enjoyable nonetheless. Missed it? Watch it in full here or below.
