Who was the 'Plain' Girl?

Watched this again last night, after a break of about 45 years, and thought that it was pretty Groovy (Am I still allowed to say that?)...

However, I would like to know who played the "Plain" girl in the group....the one with the 'nasally' voice. She was in a few scenes, but I never caught her (role) name, so I couldn't identify her from the end credits. Similarly, IMdB's cast listing doesn't help very much in identifying her.

Many thanks for any responses.
