I agree Andy it is a dilemma. I was at many a party in the 80's when we happily stomped along to a Gary Glitter number. Only a decade or so ago I sang at the Albert Hall with an all-star cast including Rolf, who managed to touch most of us girls inappropriately - one even laughed it off remarking "most of these old showbusiness-types are like that - dirty old men" as an excuse for his behaviour!
Re the statues, I believe most of them were erected because of their philanthropic work building theatres, schools, libraries etc not to celebrate their use of slaves. That needs to be made clear with a plaque or similar information board. Great to see Wales is to have a statue of Betty Campbell MBE, Wales' first black head teacher

She was a local hero when I was growing up!
