1) This rather hirsute gentleman was among the stars of 1972 comedy series His Lordship Entertains. One of his famed non-主播大秀 roles involved facial hair - although a lot less than this...
2) Concentrate on the historical female on the right who's in a tussle in this 1983 主播大秀 production of Shakespeare history Henry VI (Part I). This famed actress is less of a blonde these days and most recently known for her shabby overcoat.
3) This young actress was the titular star of Eleanor, a Play for Today outing from 1974. In the intervening years, she's become known for many roles, perhaps most renowned for sticking to her own sort.
4) Who's this hairy Bottom? Thats right, the character from A Midsummer Night's Dream. This famous man was noted for his many comic roles, including from this 1971 production.
5) This handsome bunch made a bid for Eurovision glory in the 1980 competition, but didn't make the cut. We're interested in the man second on the left, slightly obscured at the back. He wasn't mentioned in the TV listing, but these days he's regularly in the spotlight and fond of raising his paddle.
