Lost Numbers

The Lostpedia notes in its "Bloopers and continuity errors" section on the "Cabin Fever" episode that

[t]he single of "Everyday" by Buddy Holly and the Crickets [which Emily, Locke's mother, listens to not long before giving birth] was recorded in May of 1957 and not released until September 1957, over one year after Locke's birthdate of May 30, 1956.

A simple oversight, I suppose. But this week when they replayed "Cabin Fever" with pop-up information, they said Buddy Holly died in 1958. Actually, he died in 1959, so I guess this proves that Lost takes place in a universe same as ours, except one year earlier.
