… whistled in the Mobile Clinic commercials? Was it written especially for them, or borrowed from somewhere else?
Does it even have a name?
“Mobile Clinic” being a cell phone repair service, and not a medical facility on wheels.
Can you hum a few bars?
How about my favourite western tune “I Ride an Old Paint” quoted here: https://youtu.be/FBPFcEWL_FU?t=161
What city is this business in? For that matter, what country? Never heard of it.
Presumably, it’s this commercial:
I’s Mobile Klinik, not Clinic.
Sounds like something from a spaghetti western.
The Ecstasy of Gold - Ennio Morricone (The Good, the Bad and the Ugly)?
Yes, that’s it. Sorry about the misspelling. 
It definitely could be a Morricome tune, but it’s not “The Ecstasy of Gold.”
Literally. It’s “Spaghetti Time” by Alessandro Alessandroni.
Thank you! 
The Italians really are great at such things. I love it!
