However, for AD&D, you had to play a mish mash at first.  They didn't have the DMG and such stuff, or at least I didn't have it when the PHB came out, so you used the original rules for stuff that you didn't have yet.
I actually played AD&D before I ever played Basic (any version) D&D...or BX or BECMI or RC.  (If I remember correctly, it's been a LONG while since I first started).  I think I may have had Holmes at some point before I actually had all of AD&D, so it is possible I may have done Holmes prior to playing AD&D complete????
