WHEN sixteen-year-old Jill Warren wakes up, she finds Herman and the Hermits gazing down at her from the thousand pictures pinned on the walls.     She has been secretary of the group's fan club for three years.     It's Jill who enrolls new members and issues them with details and autographed pictures of the boys. She keeps members up-to-date on all the personal details of the boys and where Herman addicts can catch the group's appearances.     With fans in the States, India, Hong Kong, Sweden, Holland and France, Jill reckons she needs to be something of an interpreter to sort out some of the queries.     "Now I have organised fan clubs in other countries to cut down on the mail," says Jill. "There's a good one in the States. Herman's very popular over there."     A question Jill often gets asked by envious girls is: "How did you manage to meet Herman and get the job?"     It happened in 1964 when she entered a mime contest on Ready Steady Go, really going great guns miming Brenda Lee. Two weeks later she bumped into them again at Radio Luxembourg and Lek greeted her like an old friend. He introduced her to Herman's manager, Charlie Silverman.

When Charlie suggested that Jill might like to take on the job of the boys' fan club secretary, Jill jumped at the chance.     Since then she's been so busy answering the thousands of questions members ask about the boys that she reckons she could write a book about them.     She can reel off their sizes in socks, gloves, shirts and shorts at the drop of a hat, and even knows their fave brand of toothpaste.     But to the most popular question from the gals: "Dear Jill, please can I have Herman's home address?" - her answer must be a firm "NO."     But all the fans' letters are passed on to the boys as well as all tie pins, identity discs, gonks, cuff links and key rings that are sent by fans.     And then there are a very special pile of letters tied up with blue ribbon, which Jill hands over to the boys when she meets them. These are dozens of love letters which the boys insist on answering personally.     "I organise competitions and the winners go along to see the boys on a show," says Jill. "It's a pity that some of the fans have to miss out, but the number of seats are greatly limited to the first three rows of the theatre."     Other perks are the backstage passes which she gets for all the shows where the group is appearing. Jill has already met the Beatles, Stones and the Walker Brothers and many others.     She's a real fashion-conscious raver, who's crazy about the Dolly look and has a whole wardrobe of short, short skirts, high-waisted shift dresses and other way-out gear.
