Context paragraphs:
Out of My Bones: "Out of My Bones" is a song recorded by American country music singer Randy Travis.  It was released in March 1998 as the lead-off single from his CD "You and You Alone".  The song peaked at number two on the Hot Country Singles & Tracks (now Hot Country Songs) chart, while it was a number-one hit in Canada.  It was written by Gary Burr, Robin Lerner, and Sharon Vaughn.

A Man Ain't Made of Stone (song): "A Man Ain't Made of Stone" is a song written by Gary Burr, Robin Lerner, and Franne Golde, and recorded by American country music artist Randy Travis.  It was released in August 1999 as the lead single and title track from his album "A Man Ain't Made of Stone".  It reached number 16 on the Hot Country Singles & Tracks (now Hot Country Songs) chart and number 24 on the Canadian "RPM" Country Tracks.  It also peaked at number 82 on the U.S. "Billboard" Hot 100, making it a minor crossover hit.

Outside My Window (Sarah Buxton song): "Outside My Window" is a song co-written and recorded by American country music artist Sarah Buxton.  The song was released in June 2009 as the lead-off single from her self-titled debut album, which was released in February 2010.  It has since become Buxton's second Top 30 hit on the U.S. "Billboard" Hot Country Songs chart, as well as the highest-charting single of her career.  Buxton wrote this song with Victoria Shaw, Gary Burr and Mark Hudson.

The Living Room Tour: The Living Room Tour is a live album by Carole King released in 2005.  It consists of live recordings of most of the songs from "Tapestry".  Her daughters Louise and Sherry and background singer and guitarist Gary Burr joined her on several songs.  This album debuted at #17 in the US, becoming King's highest-charting album since 1977.  This was largely due to television advertisements and being available in Starbucks retailers.

What Mattered Most (song): "What Mattered Most" is the title of a debut song written by Gary Burr and Vince Melamed, and recorded by American country music singer Ty Herndon.  It was released in February 1995 as Herndon's debut single, and was served as the lead-off single and title track from his debut album "What Mattered Most", as well as Herndon's first Number One single on the "Billboard" Hot Country Singles & Tracks (now Hot Country Songs) chart.

All That Matters (Michael Bolton album): All That Matters is an album by Michael Bolton, released in 1997, and was his first studio album since 1993's "The One Thing".  Bolton was aided in production by Babyface and Tony Rich, and among the song writers are Bolton, Diane Warren, Babyface, Lamont Dozier, Gary Burr, and Tony Rich.  Bolton’s U.S. fans were puzzled by the album’s title, "All That Matters", until the phrase was found on the bonus track, "When There Are No Words", on the UK version of the album.  The two singles from the album, "The Best of Love", and "Safe Place from the Storm" were disappointing in sales and radio play, and fans were disappointed that the songs were performed only a handful of times during Bolton’s 1998 tour in support of the album.

Blue Sky Riders: Blue Sky Riders is a musical trio consisting of singer/songwriters Kenny Loggins, Georgia Middleman and Gary Burr.  The band released their debut album, "Finally Home", on their own record label, 3Dream Records, on January 29, 2013.
