Question: Of the three performers mentioned that Stanford Talisman performed with, who has won the most Grammys? Passage 1:Stanford Talisman is a student a cappella group at Stanford University, dedicated to sharing stories through music. Started in 1990 by Stanford student Joseph Pigato, their roots are in music from South Africa and the African diaspora, but they have since broadened their horizons to include music from all over the world. They perform not only locally in the greater San Francisco Bay Area but also around the world. Their most recent tour was to Hawai'i in the spring of 2018. The group has also traveled to South Africa (2016) and the American Southwest (2017). The group won the 1997 ICCA competition and notable performances include the 1996 Olympic Games, the White House, with 10-time Grammy award winner Bobby McFerrin in 2005 and 2019, with Seal in 2009, with Joan Baez in 2019, annually at Stanford Graduation Baccalaureate, and their sold-out 25th Anniversary Show in Bing Concert Hall in 2015.
Passage 2:He was born in Kalgoorlie to miner James Wilson and Barbara Jean McKenzie. He attended local public schools and became a teacher, graduating in 1955. After a period teaching at Mount Barker, he trained for the Anglican clergy from 1959 to 1961. From 1961 to 1965 he was the assistant priest for the Scarborough parish, and from 1965 to 1967 he taught in the United Kingdom. On 24 August 1968, he married Angela Joy Hankin, with whom he would have two sons. From 1969 he was an Anglican clergyman at Balga. In 1977 he was elected to the Western Australian Legislative Assembly as the Labor member for Dianella; he would represent this seat until 1983, Nollamara until 1989, and then Dianella again until 1993. He was the first clergyman elected to the Parliament of Western Australia following a change to the constitution. In 1981 he became Shadow Minister for Housing, Community Welfare and Youth, Sport and Recreation. He was appointed Minister for Housing, Youth and Community Services in 1983; he held this portfolio under various names until 1988, when he became Minister for Health. He left the ministry in 1992 and lost his seat at the following year's election; soon after he resigned from the Labor Party altogether.
Passage 3:Lerdorf was born on Disko Island in Greenland and moved to Denmark in his early years. Lerdorf's family moved to Canada from Denmark in 1980, and later moved to King City, Ontario in 1983. He graduated from King City Secondary School in 1988, and in 1993 he graduated from the University of Waterloo with a Bachelor of Applied Science in Systems Design Engineering. He contributed to the Apache HTTP Server and he added the LIMIT clause to the mSQL DBMS. A variant of this LIMIT clause had already been around for a decade in mainframe relational database management systems (like Oracle Rdb running on VAX/VMS, formerly from Digital Equipment Corporation), but apparently it had not yet been picked up by the emerging PC-based databases. It was later adapted by several other SQL-compatible DBMS. He released the first version of PHP in 1995.
