Guitar Hero: Aerosmith demo live? Not in Europe By Patrick Garratt, Sunday, 7 September 2008 08:31 GMT Share on: Facebook Twitter Reddit This Kotaku piece reckons a demo of Guitar Hero: Aerosmith’s gone up on Live and PSN, but if so it’s only in the US. There’s nothing on either service in Europe. We know because we checked. Hopefully we’ll get the taster sooner rather than later.
