WATCH: Miranda Lambert, Kid Rock Join Hank Williams Jr. On Stage

Hank Williams Jr. was performing "Family Tradition" at Billy Bob's in Texas on Saturday (4/3) when much to the crowd's delight, Miranda Lambert, Kid Rock and Sam Williams joined him on stage for the performance.

They also launched into an ad-libbed rendition of Kris Kristofferson’s “If You Don’t Like Hank Williams.”

One fan in attendance got the performance on tape posting to YouTube.

Miranda is set to perform a brief concert residency at Billy Bob’s in Texas later this month. The concert series will mark Lambert’s first full length, in-person, full band concerts since her "Wildcard Tour" in 2020.
