hey conny,great fan..
...of the music, where on earth did u get those killer shoes from the Jameson´s whisky advert, god they are good, please share your secret, tom
Hi Tom!
Unfortunately, one of the few things that wasn´t my own on the advert was the boots. I don´t know where they got them from. I´ve got a pair very similar to them but in suede, which I bought somewhere in Camden, London. // Conny
