Emma Only used a certain brand of hair mousse.  She was devastated when she discovered that it had been discontinued, so I always kept an eye out for any remaining cans on the shelves of any shops I went in to.  I went to Upton Park one time and found a load of them in a hair supplies superstore.  I picked up as many as I could carry.  Seeing Emma's beautiful face light up when I gave them to her made my entire day -  she had been importing them from Australia or some madness at the time!
