Review by AlsExGal

This British TV movie/special starring, produced, and written by Barry Gibb and Maurice Gibb of the Bee Gees contains a nonsensical plot, set in days of old, concerns a king (Frankie Howerd) who is dying, so he divides his lands between his two sons: Prince Marmaduke (Maurice) will inherit the Jelly kingdom, while Prince Frederick (Barry) will become ruler of the Cucumber Kingdom. The two princes set out across the land, meeting some people, singing some songs, and getting into trouble. Featuring Vincent Price, Eleanor Bron, Spike Milligan, Julian Orchard, and performances by Lulu and Blind Faith.

This is extremely silly, with little coherence, and it's aggressively unfunny. The songs are rather weak, as well, although Lulu sounds good, even if a cover of Simon & Garfunkel's "Mrs. Robinson" seems an odd choice given the setting. The Blind Faith performance is from a concert appearance, and it's awkwardly shoehorned in. This was done during the time Robin Gibb had left the group, in case you were curious why he was absent.

This episode in the careers of the Brothers Gibb is discussed in the HBO documentary "How do you mend a broken heart".
