A lot of Oklahoman Tom Paxton's & Canadian Gordon Lightfoot's songs would probably qualify as being entrenched in the American musical mind-set, as would some other Canadian writers material, such as "Circle Game."some other examples:
Last Thing On My Mind & (Can't Help But Wonder) Where I'm Bound, also Marvellous Toy; Early Mornin' Rain, If You Could Read My MInd... Seems the list could be endless.
