Last week Bethan interviewed Cardiff-based musician John Mouse, who recorded a session for Radio 1 at London's Maida Vale studios.
John was joined for the session by his TV presenter brother Steve Jones, who duetted together on the song The Last Great Rhondda Romance. The pair also agreed to be filmed for a chat, and here it is, courtesy of the BBC Introducing in Wales team.
Thanks to Ed Richmond for the video. You can see John's duet with Steve on the BBC Introducing site until Thursday 22 July.
Steve Jones is currently appearing in the Saturday night BBC One programme 101 Ways to Leave a Gameshow.
