People kept telling him, professionally and personally, that "no one cares about RnB."

"I think that's rubbish - people love that music," he said.

"It's just got to be presented well."

So Sebastian went to Memphis to prove them wrong.

He travelled to the home of blues and soul music early last year to record his latest collection of covers - the Memphis Album - in just a week with original members from the Stax Band, MGs (of Booker T fame) and the Blues Brothers Band.

"It was a real treat recording with the Memphis musicians," Sebastian said.

"It was incredible to hang out with these guys. They'd get it right the first time. I'd ask them to do something and I'd ask them `Do you want to rehearse it?' and they'd say `Nah nah, just hit the record button'," he said, putting on a southern drawl.

"It was unreal!"

The musicians are on tour with Sebastian and include renowned songwriter and guitarist Steve Cropper, who co-wrote Otis Redding's soul hit, Sittin' On the Dock of the Bay.

"I grew up on Al Green, Otis Redding, Boys to Men, Stevie Wonder," Sebastian said.

"It's great to be able to mimic my influences. This is who I am."

Sebastian said the band are "loving Australia" and he can't wait to perform at Campbelltown.

"It's really cool to perform with the greats - I mean they hung out with Elvis," he said.

"It [the tour] just keeps getting more fun."

Sebastian, who became engaged in January, said he'll head overseas after the tour to work on his next album, which will be mostly original songs. But first, he is going to take a break.

"I've got a wedding to plan," he said.

"It's all shaping up well."

Guy Sebastian performs at Campbelltown RSL tomorrow night, March 13, at 8.30pm. Tickets are $60.
