GMC Truck Promos (1979 US)

[Porn Library]

Can anyone ID the set of tunes used in the first promo of this set of promos?

These car and truck promos of the era used a lot of Bruton , KPM and Dewolfe, and the bit in the first set of promos sounds a lot like Keith Mansfield styled stuff from 1974/75 era.
