It looks like copyright might be pulling some of the old Glenn Miller Story clips off YouTube. One of my favorites was the Pennsyvania six five oh oh oh...
they "enhanced" this version with reverb, but oh well... you take what you can find. One of the others with decent sound is a record (78??), scratches and all. Good music. My mom & dad used to dance like that, Mr. Quatro. They're both big Glenn Miller and Bennie Goodman fans - actually, anything that "swings", as dad says...
"groovy", as my contemporaries used to say...
