He said, "I'm doing OK. It's difficult. (It's been a) very hard year, but I got back into it by working on touring with the Stones in Europe and doing other things, including doing this great movie ... (I've had) a lot of support ... and I appreciate that."

Jagger was on tour with the band in Australia when his long-term partner took her own life at her apartment in New York in March, prompting the group to postpone shows in Australia and New Zealand.

The veteran singer returned to the stage in Norway in May.
