Agreed, and 'country' changed to USA
'Linked Release' has not been implemented for Classical World but I will query it. It is debateable whether releases on different formats should be linked, and it probably makes better sense to link them with comments or notes
This London label release would have been for the USA, due to Decca's inability to use their own name in that country then (MCA owned it, until their purchase of PolyGram allowed the Decca name to be used worldwide). The UK release would have been this one - and why isn't there a "link releases" option here?
The Young Person's Guide To The Orchestra, performed here by The London Symphony Orchestra. The video does not name the conductor but it suggests at Britten
The Guide was first recorded by the LSO under Malcolm Sargent for the film “Instruments of the Orchestra” in 1946. They have recorded it also under Andrew Davis (1975), André Previn (1973), Charles Mackerras (1977)
