TIL: Today I Learned...

Yes and Journey helped enlarge their fan base and appeal by appearing as one of the Rolling Stones opening acts on their record-breaking 1981 U.S. /world tour in old S.F.'s Candlestick Park, Philly's JFK Stadium, and IIRC, a few other huge stadium gigs here in the U.S. and Canada. George Thorougood also opened a few of those shows, too.

That 1981 Rolling Stones U.S. tour was sort of that last gasp of the Stones still being seen or perceived as a band that teenagers and young rock fans would listen to and not be viewed as sort of older, "bygone act" from the 1960's and 70's. After this record-breaking tour, drummer Charlie Watts would unfortunately develop a pretty nasty herion addiction that would last most of the 80's and while the Stones would release two more studio albums during the 80's, a nasty personal rivalry would develop between Keith and Mick between their ongoing solo albums and that would prevent the Stones from playing any more shows until 1989. By the time the mid-80's arrived, while they may still have had a vibrant large amount of younger fans, the Stones werent really marketed to "MTV Generation" teens or rock fans in their early 20's, but as a band mostly for adults.
Living Colour opened for the Stones when I saw them during Steel Wheels and put on a much better show IMO than Mick Jagger strutting around like a chicken.
