No, Richard, it's not Paganini's No.3....neither is it No.4. It's not No.5, nor No.6. I think, therefore, you can be assured that it's
not a Niccolò Paganini Violin Concerto!
Aha, I just read this more carefully. I think it must be a piece for violin and orchestra by Paganini that's not a violin concerto.
Like, hmm ...
Polacca con variazione in A
Variations on "O mamma, mamma cara"
Introduction and variations on "Non più mesta" from La Cenerentola
I palpiti, introduction and variations on "Di tanti palpiti" from Tancredi
This is more like it, I think!
