It's been announced that HBO is to air Martin Scorsese's new documentary film, 'George Harrison: Living in the Material World.'

The film follows the life of The Beatles' lead guitarist from his musical beginnings in Liverpool through his life as a musician, a seeker, a philanthropist and a filmmaker.

It weaves together interviews with Harrison and his closest friends, performances, home movies and photographs. Much of the material in the film has never been seen or heard before in public.

In a statement, George Lombardo, President, HBO Programming, said "When Martin Scorsese brings a project to HBO, we all know it is going to be very special, and he has added to that body of work with this monumental film on George Harrison. From rock'n'roll icon to moviemaker, to spiritual seeker and humanitarian, George Harrison was a true renaissance man. This amazing film will illuminate every aspect of Harrison's remarkable, multifaceted life."

Since its debut in 1975, 'Saturday Night Live' has been synonymous with bringing pop music to the late-night, weekend masses. Now in its 35th season on NBC, 'SNL' has indeed become the holy grail for musicians.

Over the years, many memorable performances have graced the 'SNL' stage. In this list, we select the 7 best. Some were energetic, some were raw and emotive, some were quirky and fun.

But mostly, they were all daring for broadcast television at the time.
