As previously stated, these poll results do not reflect the preferences at the time. But this poll is in 2015 and
not 1967 so it reflects the preferences today.
Pink Floyd (as mentioned) were not yet in the picture but they would more than make up for it when DSOTM broke out.
Sgt. Pepper was not as well received as a lot of people my age remember it being. But the Beatles were still riding a wave of success that helped carry everything they did.
I, and my Beatle fan friends were very disappointed with the album. After the excellent Revolver album we were expecting a lot more but didn't get it.
The Moody Blues were really only known for their early hit single Go Now (I didn't know anyone who bought the album) but Days Of Future Passed changed all of that and Nights In White Satin won everyone over.
Then there was Hendrix. This album/band literally blew everyone away.
In 1967 I think this poll would be:
Hendrix (by far)
Moody Blues
Beatles
...and The Monkees really would have beaten Pink Floyd in '67.
