I listened to As Tears Go By in the 1960s and thought: What's a pretty ordinary voice doing with a Mick Jagger hit record? (I was rather naive then.) I watched her on Jools Holland's Later, and I liked the amazing musicians in the band - but MF didn't boil my kettle at all. As the years go by, her voice has become more out-of-tune and the songs are decidedly dodgy. Just to sure, I watched MF on BBC4 - and I quickly switched off again.
