It’s easy to believe that Electric Light Orchestra’s — now officially Jeff Lynne’s ELO — Over and Out Tour is a swan song. Lynne has always been a studio recluse and never a road warrior. And backed by 12 musicians on Monday at Xcel Energy Center, he declared “adios” with his opening number.

As one of last living architects of the second wave of rock, Lynne could be at the end of his career. But as a singer and band leader, Lynne has no reason to call this over and out when he could

The current iteration of Electric Light Orchestra played the first of a two-night Chicago stand on its Over and Out tour. The concert reflected — for better or worse — the technical perfectionism

"We'd all like to thank you for sticking with us," Jeff Lynne proclaimed to the throngs of adoring fans in attendance.

The legendary British band led by its driving force, Jeff Lynne, performed two consecutive nights this past Monday and Tuesday at Madison Square Garden for its farewell tour billed as ‘Over and Out.’ Both shows provided an opportunity for older and younger fans to hear the classics live from Lynne and company for the last time.

Lynne’s ELO descended upon TD Garden Monday night with a supernova of a final showdown, bidding farewell to the project with 90 minutes of rock-spiked orchestral splendor.

Lynne, 76, still sounds great vocally. Sure, he does not have the same punch as he did in the ’70s, but he still hits the high notes with ease. His recognizable voice still sounds the same over a half-century later.

That was the major takeaway from Jeff Lynne’s ELO in concert at Madison Square Garden on September 16. Famously, Lynne’s stated objective with Electric Light Orchestra was to pick up where The Beatles’ “I Am the Walrus” left off.
