This was a special programme for the ITV Telethon fund-raising event. The hunt was screened live over a 27-hour period on 29 May 1988 (Clue 1) and 30 May 1988 (Clues 2-5). 50 minutes (rather than the usual 45 minutes) were allowed to solve the five clues, and there was a different pair of celebrity contestants for each clue. With the solving of each clue, British Telecom (now BT) donated a sum of money to charity, and viewers were asked to pledge their donations by phoning 01-831-3000. When the first clue was solved BT donated £30,000 (41:18 left on clock); the second clue netted a further £40,000 (30:52 left); the third £50,000 (20:14 remaining); the fourth £60,000 (10:33); and the fifth and final clue £70,000 (with 01:14 to spare!) The total BT donation to the telethon appeal was £250,000.
