Guns N' Roses recently invited Steven Adler on stage to play two songs with the group in Cinncinati, and now that situation was repeated once more on July 9 in Tennessee.

The band played "Out Ta Get Me" and "My Michelle" again with Adler, which was cool to see… but maybe this is all a trail for the drummer to actually come back and play with the group full time? Adler is not currently touring with the group, as he was spotted on a flight back to LA the day after the gig.
