The songs mentioned were generally written by other Country Western artists, although Patsy's rendition of them brought the tunes to the top of the CW hit list.
Rolling Stones ran a survey of acidrock groupies from the 60s/70s around 1990 and asked them who their favorite artists were and who matured to enjoy as they progressed through heavier rock n roll. Nearly 90% of those polled favored Country Western singers in their later years. Interesting little stat.
