I think 2001 Armstrong nearly won Liege. Slipping seatpost in the last 20km meant he got dropped from the lead group. Jalabert used to go at them every year also. The Schleck's getting absolutely mugged by Gilbert was funny too.
Bar the Vuelta, it's debatable whether Jalabert was a real GC contender though. Even the Schlecks, you could argue that Andy's Liege win (which I remember well as I was watching it on a cycling holiday in Italy), was before he became a serious GC contender, and it was arguably his break out performance. Contador never really bothered. Quintana doesn't really bother, and of course Froome hasn't either. And these are hilly classics, much less the cobbles that Hinault and Lemond used to have a crack at.

, but yeah, it's a lovely area to ride a bike, and practically empty of cyclists, who all flood down towards Bourg and do d'Huez (usually ignoring the stunning balcony road to Villard Notre Dame the other side of Bourg). Another lovely (kinda) climb in that area that I don't believe the pros have ever gone over is the Col du Parquetout. It felt a bit like a mini Mortirolo, grinding up through forest at a horrible gradient.
