Question: Who was the lead singer on the singles Money and Us and Them? Passage 1:Born in Baton Rouge, Louisiana as an only child, he was raised on his grandfather's farm which influenced his affinity for nature and the rural life of Louisiana. His father influenced his decision to become an artist. Elemore Morgan Sr., a full-time photographer, had also worked and farmed with Louisiana architect A. Hays Town. At Louisiana State University and studied art under the tutelage of Caroline Durieux, Ralston Crawford and David LeDoux. For two years he served in the U.S. Air Force as a supply officer during the Korean War. With the help of the GI Bill, Morgan studied art at The Ruskin School of Drawing and Fine Art at the University of Oxford in England. In 1957 he returned to Louisiana began working in Lafayette with longtime friend and architect Neil Nehrbass. He served as an associate professor from 1965 to 1998 at the University of Louisiana at Lafayette (then named the University of Southwestern Louisiana).
 Passage 2:The record builds on ideas explored in Pink Floyd's earlier recordings and performances, while omitting the extended instrumentals that characterised their earlier work. A concept album, its themes explore conflict, greed, time, death, and mental illness, the latter partly inspired by the deteriorating health of founding member Syd Barrett, who departed the group in 1968. The group used recording techniques such as multitrack recording, tape loops, and analogue synthesisers. Snippets from interviews with the band's road crew, as well as philosophical quotations, were also used. Engineer Alan Parsons was responsible for many sonic aspects and the recruitment of singer Clare Torry, who appears on "The Great Gig in the Sky". The sleeve, which depicts a prism spectrum, was designed by Storm Thorgerson, following keyboardist Richard Wright's request for a "simple and bold" design, representing the band's lighting and the record's themes. The album was promoted with two singles: "Money" and "Us and Them".
 Passage 3:Robinson played for the Bermuda Under-19s in the 1995 International Youth Tournament in the Netherlands, making three appearances.
