Paul McCartney appears on Sirius XM's The Howard Stern Show today (September 5th), starting at 7 a.m. ET. McCartney, who is already busy promoting his new album Egypt Station, will appear tomorrow (September 6th) on NBC's The Tonight Show starring Jimmy Fallon, and on Friday night (September 7th) -- the day that the new album drops -- "Macca" will perform in New York City at a yet-to-be disclosed venue, which according to an inside source is somewhere "within the five boroughs."

McCartney has posted "Words Between The Tracks" clips on his official YouTube channel, which feature the former Beatle discussing the back-story to all the songs on the album. As if the promotion for the album wasn't already at a saturation point, the MTA has issued a limited run of Egypt Station subway Metro Cards.

Paul McCartney was asked if he felt it was tough over the years to have people feel comfortable critiquing his work during the recording process: "I've never thought about it, to tell you the truth, till people started to point it out; that with the reputation that I've got of having kind of done a lot, that anyone that hasn't quite done as much will be a bit, 'Oh my God -- I'm not gonna tell him -- you tell him it's rubbish!' I mean, obviously, when you've played stuff to people when you were at the height of the Beatles, it was fairly difficult for them to tell you it wasn't any good. Y'know, it's not a new thing. And so, I normally would kind of say to people, 'No, go on, I encourage you to tell me if it's rubbish,' y'know?"
