Juan Croucier claims he rehearsed with Quiet Riot and brought Frankie Banali in band back in 1981
Ratt bassist Juan Croucier has his own website, which gives a short summary of what he has been up to year by year from 1973 all the way to 2018.
Some of Croucier‘s entries for 1981 are particularly interesting and indicate:
“1981 Quiet Riot: Rehearsed and never did any show’s but did bring Frankie B. into the band.
1981 Dokken: LP “Breaking The Chains,” co-wrote, sang on.
1981 Herman Rarebell: (Scorpions) LP “Herman Ze German,” played on.”
Wikipedia does not list Croucier as ever being a part of Quiet Riot and the group is listed as inactive or disbanded in 1980 and 1981.
However, Wikipedia does state with respect to Croucier: “Croucier served as bassist for Ratt during the 1980s, and was also very briefly in Quiet Riot and DuBrow. Croucier played with Quiet Riot shortly before Randy Rhoads left to play with Ozzy Osbourne and played with DuBrow in 1981 but did not record with either. Before he left DuBrow he introduced Kevin to Frankie Banali. They went on to form a new version of Quiet Riot, resulting in the debut record Metal Health.”
