Reunions are a dicey thing.
Just ask the Eurythmics. One of the ones that worked both commercially and artistically was Bruce Springsteen 's reunion with his storied E Street Band. Springsteen and the E Streeters are celebrated for their sprawling, marathon concerts, and that sense of the epic comes across vividly. Songs routinely run seven, eight, nine minutes long. It's a mite exhausting to absorb in one listening.
