According to the website of Hamilton, Ontario's CHML, Jack Benny will be heard tomorrow night (November 13th) at 10 P.M. Eastern time.
It's the second Sunday in a row I know of that CHML is running Jack at that time.
I don't yet know if CHML runs Jack at that time every week (since I don't work for them, nor know anyone who does). However, perhaps someone can send them an E-Mail, find out, and let us know.
CHML is at 900 on the AM dial, and while 50,000 watts, it's a very directional signal. Think of it's nighttime signal area as being in the shape of a triangle, with Hamilton at one point, Boston at the second, and Atlantic City at the third.
Thus, in much of New York State (except the Adirondacks), Southern New England, Eastern Pennsylvania, and New Jersey (as well as the area in/near Hamilton, Ontario), CHML has a good nighttime signal.
Beyond that area, you can go to http://www.900chml.com at 10 P.M. Eastern time, click on a link to "listen live", and enjoy the show that way.
BTW, according to the CHML wesbite, the episode is listed as "Jack at the Hotel Pierre", which means that it probably originated from New York, since there is/was a hotel there by that name.
