I have no idea what's going on here, but somebody is playing a joke on listeners?First of all, there are, apparently, a plethora of these "1940's Christmas" CD's on the market, one being a three disc set, some being two and others being just a single disc?The songs vary from set to set to disc to disc.But some of the sound quality may be very bad. Further, Petula Clark and Rod McQuen, just to name two, are very definitely NOT from the 1940s? The may have been born then, but they did not begin performing as we know them until the 1950's and 1960's!Wish somebody would make sense out of what originally was a good idea from Collectors Choice.
