The. Whole. Album.
First Two (Sgt. Pepper's Lonely Heart's Club Band/With a Little Help From My Friends) This is great. If you don't listen to all of them, at least listen to this one.
The next one (Lucy in the Sky With Diamonds):
(Fixing a Hole)
(She's Leaving Home)
(Being for the Benefit of Mr. Kite!)
(Within You Without You)
(When I'm Sixty-Four) One of my favorites in this mash-up.
(Lovely Rita) This one is pretty good, too.
(Good Morning, Good Morning)
(Sgt. Pepper Reprise/ A Day in the Life)
