Friday night gear change

Thanks to Andrew K for submitting yet another excruciating gear change from the 1970's. They sneak in a full tone gear change at 1 minute 54 seconds, right at the start of the middle eight (in the hope you don't notice, I suppose), but they never go back to the original key, so the last verse/chorus ends up a tone higher and correspondingly squeakier than the first half. Glorious.
