At the Halle there is (on Thursdays) a pre concert discussion with a panel of experts including Mark Elder. Rusty had been invited to play spoons as an illustration of rhythm played with non-orchestral instruments.
She has used the rhythmic structure of the William Tell Overture as a basis for people who want spoons tuition (started as a joke, but there is a demand). Most are familiar with da da DUM da da DUM da da DUM DUM DUM.
Mark Elder said that the tempo was a bit slower than Rossini: Rusty invited him to sing and she would accompany - and that's what happened. Words were nonsense syllables; all conductors do this when needed.
All good fun, and a nice link between formal and informal music. Light hearted good humoured but not a piss take - it was good, ads was the concert which followed.
