For the past few years it's been not given a second thought that a popular commercial song winds up becoming the theme music for a commercial. Most bands are virtual unknowns until the gods of Madison Avenue smile in their direction, and riches can be had almost instantly.

That wasn't always the case. Many years ago it wasn't at all unusual that a popular commercial jingle would catch the audience's ear and what was once the property associated with a specific product was then turned into something of a hummable anthem.

Probably the most famous of the jingles-as-Top 40 hits was the Alka-Seltzer "No matter what shape you're stomach's in", recorded by a group of studio musicians dubbed The T-Bones and wound up its way into the Top-10 charts around the country.

Tonight it's another Ad-as Top-40 hit. This one originally began life as a Benson & Hedges cigarette commercial featuring their brand of 100 mm cigarettes. The Dis-Advantages Of You was recorded by a group of studio musicians calling themselves The Brass Ring and the rest became Pop-music history.

The world of Pop-Music and Top-40 continues.
