Dorogoi Dlinnoyu (Those Were the Days) 

In the Alfred’s book they say it’s a folk song and call it “Introduction and Dance”, but in fact it’s a Russian romance song composed by Boris Fomin and later popularized by Mary Hopkin.
There are thousands of remakes of this song and it was very familiar to me, but still took some effort to get it right.
Interestingly, it was harder to play slow rather than fast: combination of occasional staccato in right hand and legato in left took me some time. And when I sped up, these differences pretty much blurred.
Played on Yamaha DGX-660
