This will be the last week of the Spot the Oddity series, however the normal BROW will be back in February. The idea is to figure out what is different about this version of Penny Lane vs. the one you normally hear on the radio these days (i.e. the version on the Magical Mystery Tour album). The version presented here was also out officially at one time or another. As a bonus see if you can determine where (i.e. on what release) this version first surfaced. Put your answer in a comment here. Of course, if your going to try this don’t read the comments until you do (that is, if there is any, this time). Good luck to all.

When this Spot The Oddity challenge was initially posted on Mog.com, Moggers Steve Simon, Jerste, AA Coppertop and Dermahrk all came up with the correct answer. Here is the announcement of that from February 1st, 2008:
Thanks to Steve Simon, jerste, AA Coppertop and dermahrk for coming up with the right answer on the last Spot the Oddity edition of BROW. The extra piccolo trumpet riff at the end of Penny Lane was “spotted” as the oddity. The early U.S. and Canadian pressings of the Penny Lane 45 originally contained the extra riff and the track was in mono (as all the Beatles singles were at that time). The U.S Beatles Rarities album brought it back in 1980 but created a stereo version simply by tagging the riff on at the end of the album version of the song. Thanks for listening…..
