I haven't heard this one either. I did ask one of the singers at my church if she knew Careless Soul. She did not know the song. Our senior mother is 87; she comes to church about once a month. She likes the old songs. If I remember I'll bring a list of these songs and ask her about them. If she knows them, she'll sing a few bars. Do you have the melody for these songs? If so, could you make a recording of the melody and post the melodies?
