Sir Rod Stewart says his and Jools Holland's new swing album will be a "difficult sell".

The 78-year-old singer and the 65-year-old star have teamed up for upcoming 13-track record 'Swing Fever' - which will drop on February 23rd - but the 'Maggie May' hitmaker admitted the album might not be to everyone's liking at first, but he is convinced fans will want to dance to every song eventually.

Speaking about possibly playing the album live, Rod told The Sun newspaper's Bizarre column: "Having Jools and Rod on the bill is a good ticket.

"But the record is going to be a difficult sell because it’s not everyone’s cup of tea, but once you listen, you get hooked. There isn’t one track on it where you won’t want to get up and dance."

While the pair may have put together plenty of tracks to dance to - they bonded over a love of different tracks.

Both Rod and Jools are model railway enthusiasts, and Rod revealed he and Jools always catch up about their train fascination first before moving the conversation on to tunes.

He said: "Do you know about our railway fanaticism?

"When we text each other, we talk about the model railroads then the music. It should be the other way around.

"We’ve shown each other our ­collections. It is so much part of our lives.

"We go into our rooms with our layouts and our workshop."

Rod is currently on a break from his Las Vegas residency, but he recently told how he would love to return to Sin City for a "swing show".

He told the Daily Star newspaper's Wired column: "If I go back to Vegas - and I'd like to - if the album's a big success, maybe I could do a swing show, big band stuff."
