I've always been a great fan of Lulu. The Shloop shloop song in particular is one of my all-time favourites.
Here is a digitally enhanced portrait I did of her some time ago.
As you can see, it's instantly recognisable as being Lulu in her younger days, before she started messing about with Take That, and all that Benicol. I don't think I'm as much a fan of hers as I once was, but I have literally hundreds of portraits I did of her, so I might still post them for a while.
