FOR THE WEEK OF OCTOBER 29, 2018

DEAR JERRY: Over the years, I have seen you solve earworms for readers, often based on snippets used in a TV show, or commercial.

Now I've been bitten by brief guitar instrumental used in a Fidelity Investment TV commercial.

This spot begins with a couple packing luggage and headed for the airport, all the while showing their Fidelity account on a smart phone. I mention this because they have numerous commercials running, but only this one has the music in question.

I think the music is from a 1960s recording, and it has just four notes, a quick pause, then four more notes: dah, dah, dah, dah … dah, dah, dah, dah. This repeats several times over 30 seconds.

Hopefully, you can rid me of this earworm by identifying the song it's from.

DEAR DOREEN: You are right about there being many different Fidelity commercials. I found at least a dozen, but only one fit the description you provided.

Though not taken directly from the hit single, someone is playing the same eight notes that open "Little Bit O'Soul," by the Music Explosion. This 1967 release (Laurie 3380) reached No. 1 on Record World, and No. 2 on Billboard.
