Bugs Bunny is a concert pianist (I said pianist). On his big night he sits to deliver Liszt's Second Hungarian Rhapsody but must overcome a cougher in the audience, distractions in his sheet music, hunger pangs and a troublesome musical mouse living somewhere within in his grand piano.
Although this doesn't feature Bugs in the form that I'm used to him (trickery and fooling people) this is still a funny short. The plot makes plenty of imaginative little gags and never runs out of steam. The music is very good and was clearly played by a skilled pianist - it's a shame that Bugs stops us seeing how fast the real pianist's fingers move. The mouse is a good character but it is really Bugs that carries the short.
It could easily have been any character in the lead role, but Bugs brings history and weight to the role so it is more than just a lot of piano gags. He delivers the gags well and he interacts well with the audience and the mouse. The animation is not as good as it could have been but there is nothing specifically wrong with it - the same stage and single piano means that it doesn't need a great amount of effort to make it look good.
Overall this is a short with a nice simple plot that never leaves the boundary of the piano but still manages to have lots of imaginative gags from that one single device. Great music and funny delivery make for a great cartoon.
