This is cool.  Not something the current generation of *finger-sliders* will even be able to relate to, much less be able to do!  Most of them wouldn't know what a typewriter is if it bit them on the butt.  

4  minutes of fun!

This song (the typewriter part) was used in the movie But Not For Me starring Clark Gable & Lee J. Cobb (a comedy/drama) when movies were still all B&W.  I recorded that movie about 5-6 years ago and now I'm sure glad I did!
