So THAT is why Rush named that song YYZ.
Y= -.--
Z= --..
YYZ=-.---.----..
-.---.----..-.---.----..-.---.----..-.---.----..-.---.----..-.---.----.. etc.
Best. Rock Band. Ever
Yes, and the rhythm at the beginning of the song is based on the morse code for YYZ as sent on the airport transponder - I believe one of the boys in Rush was into aviation at the time they wrote that song. And of course it's their home town, and also my screen name.
