I just saw the strangest commercial on American tv- it was for legalzoom. It said"this is Frank, this is Frank's record store. Sure - Frank knows his Northern Soul but how to set up a legal limited liability company - not so much". They don't show any Northern 45's, the record playing isn't "Northern" but I think
this is the first time I ever heard the words Northern Soul used in an American ad. If anyone wants to see it- its on youtube. Type in legalzoom commerical,
and pick "The Story Of Frank".
The group was originally known as Five Pound Grin and are believed to be from San Diego, Ca. Group members were David Doran, Malcolm McCassy, Mike Lawson,
Willie Kellog, Bruce Morse and Bob Yerian.
The sleeve with The Jubilee Group would have been used for Festival. Or you could use one of these from a different Festival company. I've never seen sleeves for Jam or Northern.
