I don't know where it came from but I saw a link to a music video about a piano left in a station and some young person comes along and starts to play it. It is obviously a setup as the pianist is well known and professional but a good video nonetheless. Fantastic playing.
This prompted me to look around for more and I got the following video from YouTube. Three excellent ad-libbers on the piano and an excellent change over between short sets.
(Videos too big to upload.)
