Please answer the following question: Information:  - Andrew Powell (born 19 February 1950, Stepney, London) is an English guitarist and songwriter, and a founding member of the British band Wishbone Ash, known for their innovative use of twin lead guitars. He is named in discussions of the most influential guitarists in rock music history, often alongside other Wishbone Ash guitarists including Ted Turner and Laurie Wisefield.  - There's the Rub is the fifth studio album by rock band Wishbone Ash. It is the first album to feature guitarist/vocalist Laurie Wisefield, who would be a major part of the band's creative direction for the next 11 years. The album is considered by many to be a highpoint of the band's recording career.  - Wishbone Ash are a British rock band who achieved success in the early and mid-1970s. Their popular albums included "Wishbone Ash" (1970), "Pilgrimage" (1971), "Argus" (1972), "There's the Rub" (1974), and "New England" (1976). Wishbone Ash are noted for their extensive use of the harmony twin lead guitar format which had been attracting electric blues bands since Jeff Beck and Jimmy Page had played together in the Yardbirds in 1966. Their contributions helped Andy Powell and Ted Turner to be voted "Two of the Ten Most Important Guitarists in Rock History" ("Traffic" magazine 1989), and to appear in the "Top 20 Guitarists of All Time" ("Rolling Stone"). "Melody Maker" (1972) described Powell and Turner as "the most interesting two guitar team since the days when Beck and Page graced The Yardbirds". They have been cited as an influence by Iron Maiden founder and bassist Steve Harris, as well as Thin Lizzy and other duel guitar bands.   - Merv `` Spam '' Spence is an Irish musician & Producer , best known for his work with Wishbone Ash and Trapeze .  - Thin Lizzy are a rock band formed in Dublin, Ireland in 1969. Two of the founding members, drummer Brian Downey and bass guitarist and lead vocalist Phil Lynott, met while still in school. Lynott led the group throughout their recording career of twelve studio albums, writing most of the material. Thin Lizzy's most successful songs, "Whiskey in the Jar" (a traditional Irish ballad), "Jailbreak" and "The Boys Are Back in Town", were all major international hits. After Lynott's death in 1986, various incarnations of the band emerged over the years based initially around guitarists Scott Gorham and John Sykes, though Sykes left the band in 2009. Gorham later continued with a new line-up including Downey.  - Rolling Stone is an American biweekly magazine that focuses on popular culture. It was founded in San Francisco in 1967 by Jann Wenner, who is still the magazine's publisher, and the music critic Ralph J. Gleason. It was first known for its musical coverage and for political reporting by Hunter S. Thompson. In the 1990s, the magazine shifted focus to a younger readership interested in youth-oriented television shows, film actors, and popular music. In recent years, it has resumed its traditional mix of content.  - Melody Maker was a British weekly pop/rock music newspaper, one of the world's earliest music weeklies (according to its publisher, IPC Media, the earliest). It was founded in 1926, largely as a magazine for dance band musicians, by Leicester-born composer, publisher Lawrence Wright; the first editor was Edgar Jackson. In 2000 it was merged into "long-standing rival" (and IPC Media sister publication) "New Musical Express". 1950s1960s. Originally the "Melody Maker" ("MM") concentrated on jazz, and had Max Jones, one of the leading British proselytizers for that music, on its staff for many years. It was slow to cover rock and roll and lost ground to the "New Musical Express" ("NME"), which had begun in 1952. "MM" began its "Melody Maker" LP charts in November 1958, two years after the "Record Mirror" published the first UK Albums Chart. On 6 March 1965, "MM" called for the Beatles to be honoured by the British state, which happened on 12 June that year when all four were appointed as members of the Order of the British Empire ("Messrs Harrison", "Lennon, McCartney" "& Starr")    After reading the paragraphs above, we are interested in knowing the entity with which 'mervyn spence' exhibits the relationship of 'date of birth'.
