"Tribute shows are a perilous business. Even well-meaning homages can descend into glorified karaoke, and there's always the lurking suspicion about motive and the question of whether the event is a genuine attempt to widen awareness of the artist concerned, a marketing ploy to accelerate cult hero status or a profile-raising vanity for the participating performers."

Irwin is spot-on here, esp the last part; see Nick Drake 'tribute' shows. Watched part of one on YT with a cringingly self-possessed and smiley-smug reading of 'At the Chimes of a City Clock' by some female indie singer.
