Well.....the Bar of Music is listed in the 1945 phone book at 136 N. Center, and their phone number was 4627.

Apparently they had no advertising budget, 'cause I can't find them in the yellow pages . Oh...wait, they're listed under "Night Clubs"...but they don't have a display ad. Sorry

They aren't in the 1950 phone book at all. (And we don't have 1946-1949)

1951 phone book, the phone number is 3-9882. This time they're listed under "Cocktail Lounges" in the yellow pages, but still no display ad.

1952 phone book...no listing.

Sorry, Tentman, wish I'd come up with more for you...
