Frankie Valli -
Vocalist entertainer
His trademark a high-pitched falsetto singing style got him elected to the Rock and Roll Hall of Fame as a member of the Four Seasons in 1990 with such hits as "Sherry", "Dawn" and "Rag Doll". When his doctor told him he was going deaf due to Osteosclerosis he thought his singing career was over. Mr. Valli treated his hearing loss successfully with surgery.
