I don't think it's about the fact that he's 63, as he always says, he uses guitars for writing songs ! I think it's not about technics, because when you listen to a song like Marbletown, Hill farmer's blues, Speedway or telegraphe road and R&J, believe me, it's still there and maybe more beautiful than ever. I prefer those version then Alchemy's version... Dire Straits is done, another time, another place !
It's all about wrinting songs and telling stories with beautiful guitar touch, unique and timeless.
