Passport to the Future

Love this song, love this key change. Thanks to Paul Triggiani for playing it for me.
From the album Moog Indigo, possibly the greatest Moog pun ever.  
-Tony Trov

I Guess I'll Always Love You

I came across another H-D-H favorite of mine the other day with a similar, perhaps even more dramatic key change just before the exit: I Guess I'll Always Love You by The Isley Brothers.  Such a good track.
-Ian Harris 

Elvira

The other Elvira.
-Rahzzah 

Within

Robots engineered a key change even the numbest Humans can feel.
-Dave Kiss

Band of Gold

Listening to some Northern Soul this evening, realised that Band of Gold by Freda Payne has a wonderful key change for the final chorus around 2:20.

Yummy Yummy Yummy

For all the wrong reasons I was thinking about Ohio today, hence this little ditty by Ohio Express came to the front of my brain and would not go away.

It has a subtle but decent key change at about 1:28.  Luverly.

-Ian Harris

Earth Angel

As Marty's parents kiss and his hand becomes solid matter once more, Marvin and the boys kick it up a notch with this righteous key change, recorded live at the 1955 Hill Valley Enchantment Under the Sea Dance.
-Nick
