Roscoe Moscow, rock and roll detective was a one pager from Sounds (March 31st 1979 - March 19th 1983). Written and drawn by Alan Moore (as Curt Vile) and co-written by Steve Moore (as Pedro Henry). It was his largest body of completely unavailable work. But then the Internet got involved in the shape of 4 Color Heroes and their Alan Moore for free site.
Thanks to them the entire run of these Alan Moore strips is online at the Alan Moore Sounds Project.
