Parks and Recreation's Scott Tanner, played by Tweedy, is part of a fictional band called Land Ho!, while Andy Dwyer (played by Chris Pratt), is in Mouse Rat.

Today (16 June), a new song from Mouse Rat's upcoming Awesome Album has been released called "Cold Water", which features Tanner, aka Tweedy, on lead vocals, and a saxophone solo credited to Duke Silver (an alias used by the show's Ron Swanson, aka Nick Offerman).

Pitchfork has since received confirmation that the sax solo isn't actually played by Offerman.

"Cold Water" is out now. Mouse Rat's Awesome Album is due for release on 27 August via Dualtone,
