Anomalies in the Leonard Bernstein discography

The discography at LeonardBernstein.com appears to be very complete and authentic, but inevitably there are some anomalies. Here are some that I have observed:

Ravel: Piano Concerto in G major

The discography lists four performances:

• Philharmonia Orchestra; Leonard Bernstein, Piano & Conductor; 7/1/1946: London [RCA Victor: DMI 209 (78rpm); Camden: CAL 214 (78rpm); CD: BMG: 09026 616502; Pearl: GEMM 0066]
• Columbia Symphony Orchestra; Leonard Bernstein, Piano & Conductor; 4/7/1958: NYC [Sony: ML 5337; MS 6043; MS 6617; CD: SM3K 47166; SMK 47571]
• VPO; Leonard Bernstein, Piano & Conductor; 2/21/1971: Vienna, Musikverein [DG: CD: 4353222 GWP]
• ONF; Leonard Bernstein, Piano & Conductor; 9/20/1975: Paris, Théâtre des Champs-Elysées [Sony: CD: SM3K 47166]

The last of these, with the French National Orchestra, is listed as appearing only on SM3K 47166, which is also listed for the Columbia Symphony Orchestra performance, yet the work appears only once on that release. The ONF are not listed on the front cover. I have entered it as the Columbia recording.

Beethoven: "King Stephen" Overture

The discography lists only one performance: VPO 11/07/78: Vienna, Musikverein [DG: 2531347 p 4194392 GH; 4234812 GX6; 4310252 GBE ]. It seems there is also a 1966 recording with the NYP, owned by Sony, see Allmusic.
