for the 9th September @ the staalplaat Berlin store I infited 4 children that ride 4 tricycles on each tricycle I  mounted several radio’s and asked the kids to drive up and down the street (two on each side). I did bring my turn table out on the street that has 4 tone arms so I had 4 times stereo outputs connected to 4 fm transmitters and I did play one record . the kids were fast in down hill but not uphil and thay drove in one group. It was very nice and lots of fun, not sure about the music part.
