There’s not much more “Life In The Fast Lane” for The Eagles . After 48 shows at Las Vegas Sphere — more than any other act in the venue’s short history — the Rock and Roll Hall of Famers have only eight more gigs before officially wrapping up their Sin City run and…allegedly retiring from live music. Their final octet of Sphere shows are slated to take place on: Friday, Feb. 20 8:30 p.m. Saturday, Feb. 21 8:30 p.m. Friday, Feb. 27 8:30 p.m. Saturday, Feb. 28 8:30 p.m. Friday, March 20 8:30 p.m.
