Madonna's Tears Of A Clown intimate concert for fans

The rain has been pelting down on Madonna’s most diehard fans, who have waited 23 years for her to visit. Now they have to wait no more.

The Queen of Pop has hit the stage in an extravagant clown outfit, with a billowing yellow top and pink and white striped socks. The 57-year-old opened her Tears of a Clown show with a series of jokes before performing Drowned World/Substitute for Love from her 1998 album Ray of Light.

The mum-of-four also rode a tiny tricycle around the stage at The Forum in Melbourne to the delight of superfans.

An emotional Madonna later surprised fans by dedicating her song Intervention to her teenage son Rocco who refuses to move back to New York to live with her.

The doors were meant to open at 8.30pm but Guy Oseary then told the soaking fans, many who had camped overnight at the Forum theatre in Melbourne since Monday, that the doors would not be open before 10.30pm and the pop singer would most likely not be on stage before 11.30pm.

Fans said online the delay was because Madonna was rehearsing the show up until the last minute.

Superfans, wearing Madonna T-shirts, passed the time performing singalongs in the street before the doors finally opened around midnight.

Concertgoers have flown in from around Australia and the world - including a couple from Germany - to see the Queen of Pop. Queues stretched up Hosier Lane into Flinders Lane.

The curfew for the venue is 2am.

The fans at the intimate Forum could only win tickets via Madonna’s fan club or through Rebel Heart tour sponsor Telstra. Names have been printed on tickets to stop the money-can’t-buy tickets being scalped.
