Do you mean '77 Strings'? Yeah it has been out for about a year, but i think the vocal is pretty new. The original video for it was Fatboy at the Beach last year(you know when around a quarter of a million people turned up).
It's a good tune for sure. Did any of you hear last years radio1 essential mix from Priv? Sasha plays it near the start and it blows the doors off! How does he make any given track sound twice as good? PM me if you want a copy of the mix.
