Question:  Randolph Peter "Pete" Best has been referred to as an informal title with claims first appeared in the press immediately upon the band's rise to what?

<P0-S0> Randolph Peter "Pete" Best (born Randolph Peter Scanland, 24 November 1941) is an English musician, principally known as an original member and first drummer of the Beatles, from 1960 to 1962. <P0-S1>  He has been referred to as the Fifth Beatle. <SEP> <P1-S0> John Michael "Ozzy" Osbourne (born 3 December 1948) is an English singer, songwriter, and actor. <P1-S1>  He rose to prominence in the early 1970s as the lead vocalist of the heavy metal band Black Sabbath. <P1-S2>  He was fired from Black Sabbath in 1979 and went on to have a successful solo career, releasing 11 studio albums, the first seven of which were all awarded multi-platinum certifications in the US. <P1-S3>  Osbourne has since reunited with Black Sabbath on several occasions, recording the album "13" in 2013. <P1-S4>  His longevity and success have earned him the informal title of "Godfather of Heavy Metal". <SEP> <P2-S0> The fifth Beatle is an informal title that various commentators in the press and entertainment industry have applied to people who were at one point a member of the Beatles, or who had a strong association with the "Fab Four" (John Lennon, Paul McCartney, George Harrison, and Ringo Starr) during the group's existence. <P2-S1>  The "fifth Beatle" claims first appeared in the press immediately upon the band's rise to global fame in 1963–64. <P2-S2>  The members have offered their own beliefs of the "fifth Beatle": <SEP> <P3-S0> Reaching for the Invisible God: What Can We Expect to Find? <P3-S1>  is a book written by Evangelical Christian writer Philip Yancey and published by Zondervan in September 2000. <P3-S2>  The popularity of Yancey's 1997 book "What's So Amazing About Grace? <P3-S3> " helped boost the sales of "Reaching for the Invisible God" to the point that it appeared on religion bestseller lists immediately upon publication. <P3-S4>  Within a month, Zondervan reported sales of 94,000 copies. <P3-S5>  While preparing to write the book, Yancey asked several people how they knew that their trust in Jesus had changed their lives, and one Christian radio host responded, "I have no trouble believing God is good. <P3-S6>  My question is more, what good is he? <P3-S7>  ... I cry out to God for help, and it's hard to know just how he answers". <P3-S8>  "Reaching for the Invisible God" includes discussion of Yancey's bad experiences of growing up in a very judgmental church, a theme that he had previously discussed in "The Jesus I Never Knew" and "What's So Amazing About Grace?" <P3-S9>  and later returned to in "Soul Survivor". <P3-S10>  In November 2000, "Reaching for the Invisible God" became the first print book to be released as an e-book by Zondervan, appearing on Microsoft Reader. <P3-S11>  The book received the 2001 "Christianity Today" Book Award in the spirituality category. <P3-S12>  A "Topeka Capital-Journal" review called "Reaching for the Invisible God" "another accessible book from Yancey on a theologically complex subject for those who believe in God, and those who aren't sure if they can". <P3-S13>  David Crumm of the "Lincoln Journal Star" wrote a review of the book and said that Yancey's honesty about his own personal pursuit of God is remarkable. <P3-S14>  In a 2001 review in "The Christian Century", Peter Marty writes that Yancey "succeeds brilliantly [in] tell[ing] the truth about the Christian life 'without overselling it'".
