Passengers on trams in Birmingham are in for a surprise on BBC Music Day. The usual on-board announcements have been replaced with the distinctive voice of Ozzy Osbourne. Listen to Ozzy as you've never heard him before!
Ozzy isn't the only musician to be heard on public transport for the day. Check out Shaun Ryder on trams in Manchester, Alfie Boe on trams in Blackpool and Miles Kane on trains in Liverpool.
