Agree with Year of the Cat - quite magnificent, Slash's guitar solo's in the middle of November Rain are exquisitely beautiful but its got to be Walk On By - The Stranglers.
I thought Albatross would have a middle forty eight.
I might add the mandolin on 'Maggie May' by Rod Stewart. Saw them on Top of the Pops back in 1971, with John Peel miming the middle eight while The Faces played football all around him, promptly followed by them bowing down at his feet. Peel felt well embarrassed, but it was funny.
