I woke up this morning with this irritating earworm but couldn't remember what it was that there was something about... so, thank you! Yes, it was Tesco and it continued, "Perhaps it's the low, low prices, perhaps it's the friendly service, there's something about a Tesco you can trust".
I note you asked this question a little over six years ago, so I hope the jingle hasn't been going around in your head for all this time. Now, I hope, it will depart from mine, so thank you again for providing the only link I could find in Mr Google's vast search facility!
