Being that Axl Rose did some fill in work with AC/DC in Brian Johnson's absence it's not too far fetched that Angus would be on stage with GNR.  I'm jealous though of anyone who got to see this live, as GNR and AC/DC are in my top 5 favorite groups.

While playing in the Netherlands in July, Angus joined the GNR boys and rocked "Whole Lotta Rosie", "Riff Raff", and "Let there be Rock".  Angus even showed up to play in regular street clothes.
