Hello My Baby (Chordettes)

I purchased these tracks for a local high school quartet, They have not had too long to work with them, but they seem to be doing well, This is a song on the Wisconsin contest list so I was pleased to find tracks for them as the music itself is no longer in print. We had to get the sheet music through some sweet adeline members. I am a barbershopper myself. Thanks for your good work. If there is any suggestion, one track for each part at a slower pace might help. Thank you.
