Two for the price of one. Olga is a cleverly written syncopated version of Dvorak's Humoresque number 7. Gall has wrongly given it the alternative title of Russian Rag as Dvorak was a Czech. In my arrangement, Olga is first on the score followed by my arrangement of Humoresque. They're both fun tunes to play and it works well as a solo if they're played one after the other...Steve.
