Thank you very much man. I was just searching for it and I saw that message. It definitely sounds like a studio version to me. I can hear different guitar parts added in around 35 seconds and his vocals sound "better" than before.
mm no.. the guitar parts are just the same as in the demo.. nothing has changed... it's better mixed and you can hear it better, that's all
if you pay closely attention to the demo, you'll see the guitar is there, and it's the same, but it's more hidden in between Axl's voice and all the other stuff so you can't make the whole outro quite as clear as in the ad version without making an extra effort
