Slumdog millionaire (11)

Question

My Indian friend Jamal recently participated in the well-known TV quiz show Who wants to be a millionaire?. You might have heard or read about Jamal's spectacular success; the media reported on it extensively.

Here is what Jamal told us about the 64.000 Euro question:

I almost quit when I saw the 64.000 Euro question - I can never tell the four of them apart. But of course,I had already reached second safe haven, I had nothing to lose, and I was already taking home a five-figure amount of money. So I tried to sort them out. At first I thought the answer had to be D, because he was nowhere to be seen during that whole cucumber thing. But then I realized that naturally the twins would be together, so that eliminated answer C as well.

I sat there for a good fifteen minutes pondering the answer, trying to ignore the steam coming out of Prem's ears. Maddeningly, the part about the brother and the mother (from forty-plus years ago) kept running through my head, but it didn't help me until I remembered that it was B who had been out in front that time. I got so excited that I screamed out "THE ANSWER IS A", nearly giving Prem another heart attack in the process.

But I didn't care, because I had just won - and I don't have to tell you how much. I must say Prem acted every bit as overjoyed as I was - but I could have sworn he gave me the "fast finger" when nobody could see.

What was the 64.000 Euro question?
What were the four possible answers A, B, C, D?

Answer 1

The question was:

Which Gibb brother was not a member of the Bee Gees?

and the alternatives were:

A. Andy

B. Barry

C. Maurice

D. Robin

Explanation:

* The "cucumber thing" refers to their album Cucumber Castle, on which Robin didn't appear because he was pursuing a solo career.
* Robin and Maurice are twin brothers ("naturally the twins would be together").
* Barry and Robin shared the lead singer role, so Barry was the sole frontman during Robin's absence ("it was B who had been out in front that time" refers to this maybe?
* The "mother/brother" clue refers to the song lyrics "Whether you're a brother or whether you're a mother, you're stayin' alive, stayin' alive"
* Andy was never a member of Bee Gees, he was a solo artist his entire career, so the correct answer is A!
