Business Insider raised an interesting point about last night’s episode of Mad Men. In the episode Don Draper tries to get The Rolling Stones to sing a jingle for Heinz Baked Beans titled “Heinz is on My Side.”

This sounds a bit ridiculous, but it isn’t far from the truth. On the show, Draper tells a fan the Stones did an English cereal ad. The ad is real. Hear Mick Jagger sing about “the crackle in your face” in this 1963 advertisement for Rice Krispies.

The Stones never did an ad for Heinz Baked Beans, but The Who did, in parody at least. They released this jingle on their 1967 album The Who Sells Out to spoof their own commercial appeal. The band did real life ads, though not for Heinz.

This Tweet from writer Sean Howe is a reference to the previous episode of Mad Men that was much talked about for this awkward performance by Mrs. Draper.
