I can't embed it here, and I can't even find a way to make a link; but ITunes has the video of the Beatles playing their first US concert (at the Washington DC Coliseum in February of 1964). You can watch it for free on the ITunes site. It's unbelievably poignant to watch - the youth of the singers, the innocence and excitement of the audience, it's all just incredible and so long ago. All 4 Beatles are wearing suits and ties, for heaven's sake. The close-ups of Ringo playing the drums and of the teen girls in their plaid skirts and cardigan sweaters and cat's-eye eyeglasses screaming in the audience make it worth watching, never mind the rest of it.
And FREE - did I mention that? Get on over to ITunes and type in Beatles - you won't regret it.
