Every Electronic Organ Player knows Tico Tico by Ethel Smith, and this is one of the reasons it is so popular on the Concert scene, unfortunately it was used in the 80s by organists to see how fast they could play, and thus outdo other organists, however fortunately it is now back where it belongs, A Classic.
Apart from Ethel Smith, it would either be the version by Klaus Wunderlich on the Wersi Helios or Max Takano on the Yamaha HX1 that would get my vote.
Isn’t music wonderful?
