Thank you for everyone's votes, which were quite evenly spread. Although tyke51 got two votes, they were for separate clues, so it's buddy @12 getting two votes for his winning clue:
Catherine's true love fell off precipice (5)
Congratulations, buddy! For your prizes I had a look at Verona Rupes, a 20km high cliff on Miranda, a moon of Uranus. If you fell from the top it would take 12 minutes to reach the ground, but that is because of the weak gravity. However, you are getting something rather more predictable. Persevere with the Cliff Richard video as you eventually get a little more than The Shadows.
