Neil Young has come up with many interesting opening acts through the years. Even established acts, who normally consider themselves headliners only, will sometimes support a Neil Young tour. I had never seen an Indigo Girls performance until this tour and I believe they may have had a radio friendly hit or two around that time.
I vaguely remember the folk duo performing sn acoustic set on this Young tour

The Indigo Girls are still a touring act, and I believe they may have played a gig at The Paramount in Huntington in October after multiple Covid postponements, which is a testament to their resilience and longevity.
