What has Brian Willis the drummer been doing since being in Quarterflash?

You're asking about Brian Willis, the drummer for the band Quarterflash, but there seems to be some confusion. Brian Willis was the bassist for Quarterflash, not the drummer.

The drummer for Quarterflash was Steve Smith.

Unfortunately, specific information about Brian Willis's activities since leaving Quarterflash is scarce. There are a few things we know:

* He left Quarterflash after their first album, "Quarterflash" (1981).

* He continued playing music, but not at the same level of fame. There's no record of him joining any major bands or releasing solo albums after Quarterflash.

To find out more about his post-Quarterflash activities, you might try:

* Searching online music databases like AllMusic or Discogs.

* Contacting Quarterflash fans or music historians.

* Searching for interviews or articles mentioning him.

I hope this helps!
