I was surprised and groaned when Evergreen wafted out the CD player, it seemed like a very "easy" choice for the writers/producers. But I don't think it suited Sonai and Jamie at all, apart from anything else Sonia and Jamie were split up when this became a hit. They only got together very recently, and suddenly adopted this as "their song"? Can you imagine if Phil heard Jamie played Will Young songs over and over, he'd have beaten him up way before the Lisa incident! If it were me, I would have checked the books to see roughly when Sonia and Jamie first started dating or sleeping together and picked a well known chart song/love theme from that time.
