Mac DeMarco and Tom Hanks probably don't spend too much time in one another's vicinity but that changed on Tuesday night. The slacker rock idol was the musical guest on Stephen Colbert's The Late Show alongside fellow guest Tom Hanks, there to promote Oscar-contender The Post. The pair hooked up for a classic Instagram moment (see above) before Mac played "One Another" on the show. The track features on his latest album This Old Dog, released in May. Check out the performance below.
