Jermaine Jackson has said in a press conference that Maroon 5 are in talks to perform at a Michael Jackson tribute concert at Schönbrunn Palace in Vienna, Austria on September 26.
"I've invited R. Kelly, Stevie Wonder and many others. Stevie is making every effort to be here and I spoke to him this morning, so it looks like he's going to be here," said Jermaine. "Maroon 5 we are also speaking to, they are one of my favourite bands."
