Judy's vocal range is SHOCKING, I'll say no more about it here, just watch the video.
Most performances used in here are from 3 of her LIVE albums, but I shall leave the applicable links to most performances researched for this video in a fixed comment.
My citation of Streisand was related to people who say Judy is only good down to G3, so either these people never actually heard her live performances, or they think that she has to sing every low register note in fortissimo otherwise it's a bad note, sometimes the singer is just showcasing dynamic control in the low register like Barbra and Judy do, but ofc Judy's alto low register is heavier, darker and richer than Barbra's soprano low register.
