Robbie Williams has described his new swing album as his 'pension' and is hopeful that it will be as successful as his first.

The 39-year-old singer released his first swing album in 2001, Swing When You're Winning, and it went platinum eight times.

Speaking to The Sun, he revealed his reasons for making a follow-up 12 years later, Swing Both Ways.

"Making another swing album has always been on my mind – it's my pension. I thought it was something I'd do later on in life. Then later on in life came around pretty quickly.

"It was something I had in my back pocket that really worked and I had a great time doing it."

He continued to say he likes to alternate away from pop sometimes, "It keeps me interested, too. People have known me for 20 years now. But I could bore people if I just put album after album out. I couldn't release another pop album because I'd just done it – on my own and with Take That.

"So thankfully I have a little side project I've got going on that's swing."
