Recording year corrected 1988 -> 1973. 1988 is the year of the deutsche harmonia mundi CD issue, not of the recording. The back cover of the 2-CD Editio Classica reissue GD77059 (scan in the rip folder, Scans/Back.JPG) prints (P) 1973 against both the Lully and the Campra track lists, with (C) 1990 + (P) 1988 for the CD issue at the foot. Corroborated by https://en.wikipedia.org/wiki/La_Petite_Bande : La Petite Bande was formed by Sigiswald Kuijken in 1972 expressly to record Le Bourgeois gentilhomme under Gustav Leonhardt for DHM, "this initial 1973 recording". MusicBrainz release 9ea590c3-9ce3-4283-8079-a4e8f7c4ad44 gives 1988 as the release-group date, i.e. the issue.
