Today we publish the PaulMcCartney.com monthly newsletter for October!

Paul took to the stage in front of around 75,000 excited fans for two incredible Desert Trip performances in Indio, California, where he was joined on stage by a special surprise guest, Rihanna. He also handed control of his Instagram account over to daughter Mary for the second show, who captured some awesome photos from the desert. He followed up with an intimate 300 cap gig at Pappy &Harriet's Pioneertown Palace. To mark the end of summer, a special sale was announced over at Paul's merchandise store. And finally in this month's 'You Gave Me The Answer' fan Q&A, Paul tells us about his biggest fears, and how he overcame them.
