Bootleg CD's from the current Paul McCartney "Up and Coming" Tour are starting to appear, both for sale and for free download. Also, some DVD's made from YouTube clips have started to appear. As technology moves on, these kind of concert DVD's are getting better and better. And you can find enough clips on YouTube and similar sites to account for a complete concert! Of course, the more popular song the song is, the more clips you will find of it, and the talking between the songs are harder to find. Also, the lesser known songs can be difficult to find, as only few people would bother to film it. Still, those are exactly the kind of songs we diehards are most anxious to hear.
Meanwhile, McCartney has already started to sell tickets for his concert in Mexico on the 27th of May, one day early! So if you're planning to go, you should get over to the official site and click for tickets!
