This song could only have been done during the war when Joe Stalin was our ally .... remember all American bugs with mustache and pipe saying “ does your tobacco taste different “ they were our friend thank goodness Zhukov was on our side or that war would have went on for decades if Gerry got those oil fields
The 4th song to hit number one on Billboard. This, in 1941, probably became number one during the start of the Second World War.
