Context paragraphs:
Oh! Pleasant Hope: Oh!  Pleasant Hope is the sixth, and last, album by Blue Cheer until 1983's "The Beast Is Back".  It features less psychedelia and hard rock and includes more folk rock elements.  This is an unusual Blue Cheer album in that Dickie Peterson only sings lead on three songs.  Another unusual aspect is that the song "I'm the Light" features extensive use of the sitar and synthesizer, although on the previous album "The Original Human Being" the song "Babaji (Twilight Raga)" also featured extensive use of the aforementioned instruments.

Paul Whaley: Paul Whaley (born January 14, 1946) is an American drummer best known as the drummer for rock band Blue Cheer.  He was the son of country music singer Paul Whaley Sr.  He grew up in the towns of Vallejo and Winters California.  He played drums with a Davis, California band called the Oxford Circle.  Whaley is credited on the Oxford Circle album "Live at the Avalon 1966".  When he left the Oxford Circle to join Blue Cheer in 1967, the former band dissolved.  He was the longest-standing member in Blue Cheer other than founder Dickie Peterson in the band when it broke up in late 2009, following Peterson's death at age 63.

Lost and Found: You've Got to Earn It (1962–1968): Lost and Found: You've Got To Earn It (1962–1968) is a compilation album by The Temptations.  Released by Motown Records in 1999, it includes twenty unreleased Temptations records alongside unreleased mixes of "Ain't Too Proud to Beg" and "You've Got to Earn It".  Most of the songs were recorded during the group's "Classic 5" era with David Ruffin and Eddie Kendricks as lead singers, although there are some tracks present which were recorded with Ruffin's predecessor, Elbridge Bryant, in the lineup.  There's also one track that was recorded with Ruffin's successor, Dennis Edwards.

David Ruffin: David Eli Ruffin (born Davis Eli Ruffin, January 18, 1941 – June 1, 1991) was an American soul singer and musician most famous for his work as one of the lead singers of The Temptations (1964–68) during the group's "Classic Five" period as it was later known.  He was the lead voice on such famous songs as "My Girl" and "Ain't Too Proud to Beg".

Statue of a Fool: "Statue of a Fool" is a song written by David Ruffin and recorded by many country artists.  It was first recorded in 1969 by country music artist Jack Greene where it was released as a single and became a number 1 hit.  Brian Collins recorded and released it in 1974 from his second album, "This Is Brian Collins".  It peaked at number 10 on the country charts.  David Ruffin, formerly of The Temptations, also recorded a version of the song in 1975.  Bill Medley, formerly of The Righteous Brothers, also released a rendition in 1979 that went to number 91 on the same chart.  In 1989, it was recorded by country music artist Ricky Van Shelton, who released it as a single from the album, "RVS III".  It peaked at number 2 on the "Billboard" Hot Country Songs chart and hit #1 on the Canadian "RPM" country singles chart.

David Ruffin (album): David Ruffin is the self-titled album from singer David Ruffin.  Coming out after Motown refused to put out his proposed third album in 1971 (released as "David" in 2004), Ruffin was likewise no longer afforded access to "A-list" material and support musicians.  This album in many ways was a collaborative effort with Bobby Miller, who produced the album.  Miller also had a hand in composing eight of its tracks.  Although the album made it into the US R&B Top Five, it underperformed on the US pop charts, peaking at number 168.  Those slipping figures were indicators of the increasing lack of interest from Motown in Ruffin's career.

Dickie Peterson: Richard Allan Peterson (September 12, 1946 – October 12, 2009) was an American musician, best known as the bassist and lead singer for Blue Cheer.  He also recorded two solo albums: "Child of the Darkness" and "Tramp".

The Beast Is Back: The Beast Is Back is the seventh album by a newly reformed Blue Cheer, 13 years after their previous album, "Oh!  Pleasant Hope" (1971).  It contains re-recorded versions of some of the band's most popular songs from their late-1960s heyday as well as new material.  The album features founding members Dickie Peterson and Paul Whaley.  Original guitarist Leigh Stephens did not participate in the reunion.

Temptations Live!: Temptations Live!  was the first live album to be released by The Temptations.  Recorded on October 3, 1966 in the Upper Deck of the Roostertail Club in Detroit, Michigan, and released on album by Gordy (Motown) Records in 1967, the album features David Ruffin, Paul Williams, Eddie Kendricks, Melvin Franklin, and Otis Williams performing their regular live repertoire for a highly receptive crowd mostly consisting of young women.  Included in the set are Temptations hits such as "My Girl", "My Baby", "Get Ready", "Ain't Too Proud to Beg", "Don't Look Back", and the group's then-current single, "Beauty Is Only Skin Deep".  Out of the several live albums the group recorded during their career, this is the only one to feature David Ruffin.  The album remained on the Billboard 200 album chart for 51 weeks peaking at number 10.

I Am My Brother's Keeper: I Am My Brother's Keeper is a 1970 album by Motown vocalists and siblings Jimmy Ruffin and David Ruffin, credited as "The Ruffin Brothers".  The album includes the singles "Stand by Me" and "When My Love Hand Comes Down".
