I am officially...
...my mother's daughter.
I just realized today -- almost 33 years late -- that the song 'Penny Lane' is 'Penny Lane', not 'Elaine'.
Sigh.
It's not quite on the same level as mishearing 'The Traveling Wilburys' as 'The Battling Ovaries', but I think I get points for the whole MISHEARING THE SAME SONG FOR THIRTY YEARS thing.
[ETA: Well, it's not a total tragedy, as this revelation led me to discover that there's a literal video version of the song.]
