Star Wood set for a Wizzard night out.
A number of routes were closing between 4pm and 6pm to make way for Santa and his reindeer.
The parade was starting outside Marks & Spencer in High Street at 4.30pm and taking in many of the city's busiest streets.
Brummie rocker Roy Wood, of ELO and Wizzard fame, will be inducted into the Broad Street Walk of Stars at the end of the parade in Brindleyplace at about 5.30pm.
Special events are being staged to tie-in with the procession, including a family activities workshop by a reindeer pen at the start line and a magical illuminations display at St Philip's Cathedral. A Christmas Galleon show is being held in Victoria Square and a Heliosphere aerial display in Centenary Square.
It's part of a programme of festive events in the city, including the Frankfurt Christmas Market opening on Thursday.
