Flight of the Conchords Work Out Messy Family Drama in New Song 'Father & Son' On 'Colbert': Watch

Flight of the Conchords on The Late Show with Stephen Colbert on Sept. 24, 2018.

If you know anything about New Zealand comedy duo Flight of the Conchords, it's that their wit is drier than the Sahara Desert in the summertime.

This might explain why Bret McKenzie and Jemaine Clement didn't really have a "funny" answer for where they've been since going on hiatus in 2009 when superfan Stephen Colbert asked them about the long break on Monday night's (Sept. 24) Late Show.

"We've just been getting ready for tonight," McKenzie said about what the duo have been up to all these years. Truth be told, they've had some children (not together, mind you, but separately), plus they've made some movies and did a bit of touring recently that will debut on HBO as Flight of the Conchords: Live at the London Apollo on Oct. 6. When Colbert suggested their audience had aged along with them, Clement argued, "It seems like we've gotten more older to me." 

After going down a dark, weird road with an extended metaphor about fame as a horse, the duo took to the stage to debut a brand new acoustic ballad "Father & Son." And, in typical FOTC fashion, what began as a lovely back and forth Cat Stevens-esque dialogue between a loving "guy and his little guy" turned super weird when Clement tried to calm McKenzie's fears in the wake of mom's death.

"You know very well dad momma didn't die/She just hooked up with another guy/His name's Trevor and now they live together/That's why you pick me up on Friday nights," McKenzie sang back. Bottom line: marriage is hard and kids are way smarter than you think.
