Question: Which artist who released the album "Hello, I'm Dolly" has collaborated with Kathy Mattea?
Sentence (from "Dolly Parton"): With steady success during the remainder of the 1960s (both as a solo artist and with a series of duet albums with Porter Wagoner), her sales and chart peak came during the 1970s and continuing into the 1980s; Parton's subsequent albums in the later part of the 1990s were lower in sales.
Relevant evidence: No
