Corrected entry: When Lisa is researching artist Johan Oldenveldt, it says he was born 6 May, 1942 and died 38 years earlier on 5 December, 1904. (00:06:50)
Corrected entry: Lisa is singing "One (Is the Loneliest Number)" and looks up the composer to find out that he "died of a heart attack suffered on Valentine's Day." Although Harry Nilsson DID suffer a massive heart attack on 14 Feb 1993, he didn't die of heart disease until 15 Jan 1994.
Correction: Lisa's search said 'Harry Nilsson - Died of massive heart attack SUFFERED on Valentine's Day'. The operative word here is 'suffered'; so what that means is Nilsson died (eventually) of a heart attack that began on the 14th of February the year before. It's tricky semantics, yes but it's correct. It would've been a mistake if he'd said 'died of massive heart attack on Valentine's Day'.
Correction: The article she looks at shows his lifespan as 6 May 1859 - 5 December 1932.
