This is "By Your Side" from Getaway's "II" demo (I guess that means that this was their second one...) from 1990 (judging from the signature of the artist that designed the cover of the tape that I own) although the year of its release is a speculation of mine as well.
Getaway were a band from Nürnberg, Germany, that only managed to release one full-length album, 1994's "(No) Leave Without Paying" via Gorgon Records. An original copy is quite rare and expensive now but you can also find a 2006 version of Time Wrap records circulating around.
"By Your Side" was the only song from this demo that the band re-recorded for their sole album, so I guess they loved it as much as I do. One of the best Queensryche-like stuff I've heard from Germany!
Getaway were:
Andy Oeder: guitar
Manny Hammerand: guitar
Roland Arnold: bass
Rami Ali: drums (later got to play with Evidence One and even on the Kiske/Somerville project)
Jürgen Kirsch: vocals (listed as "Ric" on the demo, but I believe it's the same guy as the CD)
P.S. If anyone from the band is reading this, please provide us with more info -- thanks!
