Okay, it's not a jingle. But I remember an animated commercial for Gunther beer. I saw this in Washington D.C. in either the late '50s or, possibly, the early '60s (the '50s is more likely.)

A maestro/conductor is standing on a podium, in front of an orchestra, and he says "Give me a G." Immediately, a bottle of Gunther beer appears in the air.

He says "Give me a G major", and a bottle of Gunther beer with a military hat on appears in the air.

He says "Give me a G minor", and a bottle of Gunther beer with a miner's hardhat and lamp on appears in the air.

He says "Give me a G on a scale", and a bottle of Gunther beer standing on one side of a pan balance appears.

Increasingly frustrated, he says "Give me a G I can hear", and a bottle of Gunther beer appears in the air, slowly pouring into a mug (we hear the glug, glug, glug sound as it pours.)

Admitting defeat, the conductor leaves the symphony hall and trudges down the street, muttering to himself "I ask for a G ... they give me a G ..."), and he notices that he is standing right outside a tavern. So he says "Why not?"

He goes into the tavern and says "Give me a nice, cool G!", and the bartender and all of the other patrons turn to him and hum a G chord. I think he faints at that point.

I couldn't find it on YouTube. Maybe I didn't look hard enough.
