Heart and Soul piano duet 

Heart and soul in a Stenway and son's piano... Actually, quite inadvertently, it starts with Blue Moon, then comes original Heart and Soul, followed by famous Monty Pythons' "Always look to the bright side of life" whistle, then we get to the point which clearly inspired the creators of Ipad Mini advertisement, and as a whole, you simply get what my sister and I call "our song". There is no score for this because we were improvising, and the funny thing is I was totally unaware of the fact that I was using Monty Python's tune. We simply kept playing until the song naturally ended. We are really glad that so many people liked it. Thank you all!
PD: By reading your comments I noticed that some people were really concerned over the picture hanging on the wall: it's just an oil painting of a nude, there are plenty of them in museums!
