Plus the exposure is a good thing- I dare say a lot of people watch that show. It always seems to be on in public places when I'm out & about.
This will be the most-watched thing Neil’s done in a long time, I believe. His last really major American appearance was probably when Crowded House were on Jimmy Fallon for Intriguer (this was pre-Tonight Show). But Ellen has probably double that show’s audience — **4 million** eyes will be on the band, and Neil. Interesting times indeed.
