Apparently you haven't seen my previous attempts at puzzle-solving.

"Uh, Zorro is the only one that starts with the letter 'Z'?"

But, luckily for me, there are search engines:  www.tartareandesire.com/bands/Zorro/5440/

"The British hard rock / heavy metal band Zorro was formed in Norwich in 1975. A highly collectable single was released in 1979 before the band split up with bassist Alan Fish moving on to acts such as Tredegar, Groundhogs and Egypt. The band did a two month UK tour following up their EP release and had the chance to support bands such as Suzy Quattro and Dire Straits during their life span."

U.S. audiences will remember Suzy Quattro for her tight-leather-pants-clad appearances on the tv show "Happy Days" as "Leather Tuscadero", the younger sister of "Pinky Tuscadero".  I know I do.

"Former Members:

Mark Newman (Vocals)

Dave Smith (Vocals)

Terry Bunting (Guitars)

Ronnie Newson (Guitars)

Kevin Longman (Bass)

Alan Fish (Bass)

Galen Littlewood (Keyboards)

Jon Kirk (Drums)

Fritz Wright (Drums)

Ricci Titcombe (Drums)"

So, what is the single, and is it available on-line?

Arrods Don't Sell'em is available from Vinyl Tap of Huddersfield @ £59.99
Otherwise the question was rhetorical. I sort of know where some of the others are now – their names crop up, but Zorro’s, perhaps because they are from Norfolk not London don’t.
