I just sold out that Fillmore
Likely refers to San Francisco’s famous Fillmore Auditorium where Mac played a sold out show in 2011.
Could also be a comment on his show at The Fillmore in Silver Spring, MD, described by a Washington Post music critic as “the single worst concert I’ve been to all year”. To be fair, that critic was well out of Miller’s target audience at 32 years old. Age-appropriate fans seemed to like it.
