LOS ANGELES: The long-awaited Guns N’ Roses reunion got off to a surprise early start Friday, with the band playing a show at a small Los Angeles club where the rock legends were first noticed.

Before a lucky 500 fans packed into the Troubadour in West Hollywood, singer Axl Rose and guitarist Slash performed for the first time together in public for more than two decades.

Videos posted online showed the 54-year-old Rose — still with flowing blond hair but without his once constant bandana — singing alongside Slash in his trademark top-hat over his black curls.

“You know where you are?” Rose yelled in his soaring voice in the signature line of “Welcome to the Jungle,” according to one segment shot by a fan — a technology that did not exist in the band’s glory days.

Social media posts said that Guns N’ Roses started the show with “It’s So Easy,” an energetic song with a bad-boy attitude that has frequently been the band’s opener.

Years of rumors of a Guns N’ Roses reunion came to fruition earlier this year when the band was announced as headliners for the Coachella festival, which will take place later his month in the California desert.

The band has since announced a full tour at arenas but had suspiciously left off any date in their native Los Angeles.

Guns N’ Roses early Friday announced the show for the evening. Some fans online initially thought that it could be an April Fools’ Day prank, but the band soon confirmed that tickets would be available — only in person and one each — at a “retro” price of $10.
