In recent days, Billy Joel has really been leaning into his status as a rock ‘n’ roll elder, especially in his regular gigs at Madison Square Garden, effectively his second home. Just in the past few months, Joel spearheaded the campaign to induct Warren Zevon into the Rock And Roll Hall Of Fame, and he covered Zevon at MSG. He’s also paid tribute to his generational peer Jeff Beck with a pair of covers. In LA a couple of weeks ago, Joel performed with Stevie Nicks. And last night, Billy Joel invited ZZ Top legend Billy Gibbons to his stage.
