I was also wondering if BBC Wales were doing another "Coming Home" series showing celebs with Welsh ancestry re-visting their roots (previous programmes saw Patrick Mower, Janet Street Porter, Rolf Harris among others) as a few months ago my mother saw a film crew in the next street in Tonypandy (Rhondda Valleys) filming Glyn Houston at his old family home.
Interestingly for me, as a child my grandfather and his siblings lived a few doors up from Glyn, Donald and their sister Jean and I have a photograph of my grandparent's wedding (grandmother from my profile) where Glyn (as a young boy) is standing on the side watching the bride and groom leave the church, so it would be great to see a programme made about someone who grew up in the same street as my own family!
