There are many for which tunes are unknown. Some are from 16th or 17th century manuscripts, and it is not clear whether they were ever meant to be sung, or, practically the same thing, it is not known whether they were ever sung. On the other hand there are over 100 traditional tunes for some of the Child ballads, so which ones should be recorded? There is a set of 8 records of Child Ballads sung by Ewan MacColl and A. L. (Bert) Lloyd, with a supplementary record of 'Childlike' ballads not included by Child.
