Mick Jagger turns 80, knows his best songs 2:33

(CNN) -- Mick Jagger's eight children may not want to read this.

In a recent interview with The Wall Street Journal, the rocker opened up about the Rolling Stones' business as the band prepares to release their first album of original material in 18 years.

Jagger says that while he doesn't like to deal with the business side of the music industry, it's necessary.

The Rolling Stones have made millions from their tours over the years. When asked if there were plans to sell his post-1971 music catalog to make even more money, Jagger said no.

The rocker added that his "children don't need $500 million to live well" and hinted that he might one day donate his fortune to charities, according to the publication.


Jagger's eight children, Karis, Jade, Elizabeth, James, Georgia May, Lucas, Gabriel and Deveraux, range in age from six to 52.

The 80-year-old musician said he is also aware that money can still be made.

"Now you can have a posthumous business, can't you?" he said. "You can do a posthumous tour."
