After I informed the players which of those prestige classes existed in my campaign (varies depending on which I am running), I would say "You may well be planning to take that combination of classes, but you will have to work that out in game. The idea that you could find a teacher of some sort for each of those prestige classes right when you want to take them is a bit hopeful." In my experience, (echoing what others have said) a lot of builds that look really good at level 20 are quite weak at low to mid levels.
I'm sure the other 1st ed.ers is this thread already know this, but the Fochan Lyrist (or whatever) is designed to be like the odd 1st edition bard, who need to take 6 or so level of fighter and then thief before taking levels in the druid-spell-casting bard. Given the oddities of 1st ed. dual classing, I'm not sure how well the FL simulates that; but its a way better attempt than the one I came up with for my Greyhawk campaign.
