The Fleas were a studio-only pop-rock vocal group who issued one single for the Challenge label in the early 1960s, "Tears"/"Felicia." Their 45 would be forgotten today if not for the involvement of Rick Nelson, who was one of the singers in the group, which also included a young Glen Campbell, Jerry Fuller, and Dave Burgess. Nelson had to keep his involvement low-key and unpublicized, as he was under contract to a different label, Imperial, for his solo recordings. There was no threat, though, of the single blowing his cover, since it was a generic early-'60s effort crossing teen idol pop with doo wop and novelty rock'n'roll. Both of the tracks can be heard on Varese Sarabande's CD compilation The Lost '60s Recordings, which also includes six songs Nelson did with the same musicians (and Jerry Fuller's brother Bill Fuller) on 1961-62 singles credited to the Trophies, as well as solo recordings from the era by Campbell, Fuller, and Burgess.
