Last night we went to see the Ukulele Orchestra of Great Britain at the Corn Exchange, Newbury. It really was a wonderful evening - full of fun and laughs. It was wonderful to see and hear six people all with their hands going up and down rapidly (strumming the strings!) and hearing the rapid plinkity, plink of the ukuleles together. (Although, they explained that the different sizes of Ukuleles have different sounds - one goes plink and another goes p-l-i-n-k for example. And the thing I thought was a guitar at the end was actually a bass ukulele.)
They did some wonderfully original routines. Their one genuflection to George Formby was "Leaning on the Lampost" in the style of a group of Russian balalikas, complete with Russian-style chorus and a Russian-accented lady responding. Sounds strange. But it was hilarious.
If you get the chance to see them, grab it.
