Question: James Walsh and Terry Glaze, have which mutual occupations?
Context: Michael James Walsh (born January 6, 1945 in Toronto, Ontario) is a Canadian film critic and print journalist.  In addition to newspapering, Walsh has been a broadcaster and public speaker, published works of film history and run for Canada's Parliament. Terrence Lee Glaze (born November 29, 1964, Columbus), known as Terry Lee, is a Texas-raised singer and guitarist who is most known for his work in American heavy metal bands Lord Tracy and Pantera. Gypsy was an American progressive rock band from Minnesota, formed as The Underbeats (1962–1968).  Gypsy was the house band at the Whisky a Go Go, West Hollywood, California for about eight months from September 1969 to 1970 and were known in 1970 for their US "Billboard" Hot 100 single "Gypsy Queen Part 1 and 2".  Most of Gypsy's music was composed and written by guitarist and singer Enrico Rosenbaum.  Drummer Bill Lordan went on to play with Sly & the Family Stone and a long career with Robin Trower.  Keyboardist James Walsh continued the band in various incarnations as The James Walsh Gypsy Band. James Milne Walsh (born 10 June 1980 in Wigan) is an English singer, songwriter, guitarist, pianist and frontman of the band, Starsailor. Pantera was an American heavy metal band from Arlington, Texas.  The group was formed in 1981 by the Abbott brothers – drummer Vinnie Paul and guitarist Dimebag Darrell – along with lead vocalist Terry Glaze.  Bassist Rex Brown joined the band the following year, replacing Tommy D. Bradford, who was the unofficial original.  Having started as a glam metal band, Pantera released four albums during the 1980s.  Looking for a new and heavier sound, Pantera replaced Glaze with Phil Anselmo in late 1986 and released "Power Metal" in 1988.  With its fifth album, 1990's "Cowboys from Hell", Pantera introduced a groove metal sound.  Pantera's sixth album, 1992's "Vulgar Display of Power", exhibited an even heavier sound. " Far Beyond Driven" (1994) debuted at number one on the "Billboard" 200. Starsailor is an English post-Britpop band, formed in 2000.  Since its formation the band has included guitarist and vocalist James Walsh, drummer Ben Byrne, bassist James Stelfox and keyboardist Barry Westhead. James Andrew Walsh (20 November 1908 – 17 May 1985) was a hurler.  He was born in Waterford, Ireland, the son of James Walsh of New Ross, Co.  Wexford, and Ellen Stafford of Carrick-on-Bannow, Co.  Wexford.  He attended Mount Sion in Waterford City, the first school founded and run by the Congregation of Christian Brothers.  The Irish Christian Brothers were staunch champions of Irish nationalism, the Irish Language Revival and Irish sports.  Mount Sion established a strong and enduring tradition of hurling, which filled the young and impressionable Jimmy with a lifelong enthusiasm.  When he left Mount Sion, James took with him not only the skills, but a determination to excel, which eventually led to his participation in the All-Ireland Senior Hurling Championship of 1934. Unlock the Gates is the fourth and last album by the rock band Gypsy.  Keyboardist James Walsh continued the band in various incarnations as The James Walsh Gypsy Band.  The horn section is from the band Chicago. I Am the Night is the third studio album by heavy metal band Pantera, released in 1985 through Metal Magic Records.  The album was made available only on vinyl and cassette, with any subsequent CD releases being bootlegs transferred from the vinyl or tape originals.  Some of Pantera's faster and heavier influences are more apparent on "I Am the Night", especially on the title track, "Valhalla" and "Down Below" (which was re-recorded for their next album "Power Metal").  Guitar solos took on character, hinting at Dimebag Darrell's later style.  It was also the last album to feature lead singer Terry Glaze.  The band made their second music video for the track "Hot and Heavy". James Walsh (28 May 1913 – 5 July 1986) was an Australian cricketer.  He played fifteen first-class matches for Tasmania between 1932 and 1937.
