Here's the complete Maybe I'm Amazed, published by Paul McCartney yesterday:
Here's Silly Love Songs, published by Specticast april 17.
and here's a trailer, published by Specticast on april 15.
If you can't make it to a theatre near you on the day (well, I'd have to travel through several countries to see it), there's always the Blu-ray and DVD release June 10 (11th in the USA). What you'll miss then, is the new 12-minute interview with Paul, which will only accompany the theatrical version of the film. Although I must confess, I wouldn't be at all surprised if it shows up elsewhere.
