Ahead of his upcoming run of shows in The Olympia, Keith Barry performed on Brendan O'Connor's Saturday Night Show last Saturday. The performance caused quite a stir on Twitter with people lauding and lambasting in equal measure. To be fair Keith took many of the negative comments on the chin, even retweeting many. You can watch the clip (for the next 20 days) on the RTÉ Player here. And you can follow Keith on Twitter here. Keith plays Dublin's Olympia Theatre from 10th July and you can book tickets here.
