Well, the title sums it up, Noel doing Slide Away during an acoustic set in Chicago in 1998. I'm not sure where exactly in Chicago...sorry. But it's still amazing and Noel needs to bring his acoustic set back!
Also thought I should mention that I did not take this video and I hope it is ok with whomever did, this is NOT my work and I'm not trying to claim it is mine. I just thought it was lovely and it should be shared with other Oasis fans.
