Question: What is the birth date of the singer of Some Lessons Learned?
Context: Thomas Day Singleton (Birth date unknown – November 25, 1833) was a United States Representative from South Carolina.  He was born near Kingstree, South Carolina but his birth date is unknown. Astro Boy (アストロボーイ・鉄腕アトム , Asutoro Bōi: Tetsuwan Atomu , lit.  "Astro Boy: Mighty Atom") is a remake of the 1960s anime series of the same name created by Osamu Tezuka, which was produced by his company, Tezuka Productions, Sony Pictures Entertainment Japan, Dentsu, and Fuji Television network.  It was also shown on Animax, who have broadcast the series across its respective networks worldwide, including Japan, Southeast Asia, South Asia, East Asia, and other regions.  It was created to celebrate the birth date of Atom/Astro Boy (as well as the 40th anniversary of the original TV series).  Under the original English name (instead of "Mighty Atom"), it kept the same classic art style as the original manga and anime, but was revisioned and modernized with more lush, high-quality, near-theatrical animation and visuals.  It combined the playfulness of the early anime with the darker, more serious and dramatic Science fiction themes of the manga and the 1980 series.  The anime broadcast in Japan on the same date as Atom's/Astro's birth in the manga (April 6, 2003) across Animax and Fuji Television.  It was directed by Kazuya Konaka and written by Chiaki J. Konaka at the beginning of the series.  Other writers included were Keiichi Hasegawa, Sadayuki Murai, Ai Ohta, Hirotoshi Kobayashi, Kenji Konuta, and Marc Handler, who was also executive story editor. Hippolytus or Hipolit (died c. 1027) was an early medieval archbishop of Gniezno.  His place and date of birth date are unknown but the medieval historian Jan Długosz claims that he was of noble birth and a Roman citizen.  Modern scholars generally agree that he was not Polish.

Jean Boisard (also Boizard) was a learned Frenchman, who died around 1725.  His birth date is not known.  He is considered to be one of founders, in the 17th century, of numismatics, the science or specialized knowledge and collection of medals and coins.  He was Counsellor at the French royal “Cour des Monnaies”.  In 1692, he published a short treatise on coins, entitled “Traité des Monnaies, de leurs circonstances et dépendances”.  In his book (which was reprinted several times during the first quarter of the 18th century), very precise and accurate details were given on alloy and on manufacturing secrets.  As a result, the government forbade its circulation, being afraid that it could be used as a guidebook for counterfeiters.  There are still some rare copies available, which are consulted by contemporary specialists of numismatics. Lessons learned or lessons learnt are experiences distilled from a project that should be actively taken into account in future projects. Lessons Learned is the sixth studio album released by country music artist Tracy Lawrence.  It was also his last album for Atlantic Records before the closure of Atlantic's Nashville division in 2000.  This album produced three singles for Lawrence between 2000 and 2001: the title track, "Lonely", and "Unforgiven", which peaked at #3, #18, and #35, respectively, on the "Billboard" country singles charts.  "Lessons Learned" was also Lawrence's first Top Ten country hit since "How a Cowgirl Says Goodbye" in 1997. The Aotearoa New Zealand Development Studies network (DevNet) came about to link together New Zealand's 'development community' to foster dialogue and information sharing.  In 1993, Massey University organised the 'Development that Works: Lessons from the Asia Pacific' conference.  It brought together for the first time a diverse array of development representatives to discuss successful (and not so successful) initiatives and the lessons learned from these. Some Lessons Learned is the fourth album by singer and actress Kristin Chenoweth.
