Leonid Hambro has composed piano variations in the style of Beethoven on the tune 'Happy Birthday to You.' These variations are very well crafted and are for the advanced pianist. Some of Beethoven's most popular pieces are used including: Bagatelle, Op. 119 * Minuet in G * Pathetique Sonata * Moonlight Sonata * Für Elise and the theme from Symphony No. 5. These variations are great fun to play with flare.
