You can't make this stuff up.

In 1986, Javier found himself back on the payroll, after a mishap at the Wembley Concert at two different points in the show.  The sequencer went out of tune during Stone Cold Crazy and couldn't be fixed in time for Tutti Fruitti.  Those two cuts have been edited out of every version of the Wembley concert that I've found.

Unfortunately, the US tour did not happen.  By the time The Cosmos Rocked, Javier had died homeless and penniless and never found his place on stage. 

Ask John.  That's why he left.
