Donovan Leitch (yes, that Donovan, of 1960s "Mellow Yellow" fame) has crafted a new collection of sonically vibrant songs for kids on Pied Piper, his third children's recording. Donovan's voice is unmistakable on tunes like the new more kid-friendly version of "Happiness Runs," sung in rounds. Other favorite tracks given new life include "Mandolin Man and His Secret" and "Sun Magic." As a bonus, listeners are treated to back-up vocals by Aine Whelan, a handful of Music for Little People child vocalists and Donovan's own grandchildren (Music for Little People, 800-409-2457, cassette $10.98, CD $16.98, all ages, Mar.)
