Rock Legend's song inspired by aliens

At some point in the past 20 years, George (or one of the rent-a-hosts) revealed a famous rock star was not only a great C2C fan, but had actually called in, on air, under another name on multiple occasions.

Hagar was one of the names that was thrown around in BG, along with Rod Stewart and Joe Walsh.
 
I wonder if there is a drug association with alien contact and rock stars. The two seem to go tog.
