Beasts

Beasts was a series of unrelated plays written by Nigel Kneale (of Quatermass and The Stone Tape fame) that all share a theme of light horror. Special Offer stars Pauline Quirke, who must have been only about 16 at the time. Buddyboy stars Martin Shaw sporting quite a perm.
Also on the disc is another similar play Kneale wrote for the Against The Crowd program the previous year.
