I never cared for CSN-Y (though I liked the Hollies--Bus Stop, Just a Song Before I Go, loved the Byrds, and didn't care for the Stephen Stills contributions to Buffalo Springfield). Too fluffy for my taste (though Marakesh Express is certainly catchy and enjoyable --a good choice for the summer challenge-- and the Wooden Ships collab is brilliant). But Deja Vu (and I normally hate really popular music) is worth its fame.
