Shaken Not Stirred and Greatest Hits In 2004, Vassar released his third studio album, Shaken Not Stirred. The album produced Vassar's second No. 1 as a singer in the song "In a Real Love". Also released from this album were the No. 17 "I'll Take That as a Yes (The Hot Tub Song)" and the No. 22 "Good Ole Days". Unlike with his first two albums, Vassar recorded Shaken Not Stirred with his road band. Vassar produced the album with Nick Brophy and Frank Rogers. Vassar's first greatest hits compilation, Greatest Hits, Vol. 1, was issued in 2006. This album comprised the biggest hits from his studio albums to that point, as well as his renditions of "Bye, Bye", "I'm Alright", "My Next Thirty Years", and "Little Red Rodeo". The album also included three new songs. Two were released as singles, starting with the No. 2 "Last Day of My Life", which Vassar was inspired to write after attending the funeral of his friend Robert Byrne, with whom he co-wrote his 2001 single "Rose Bouquet". The second and final single from Greatest Hits, "The Woman in My Life" (another song co-written by Vassar and his wife), reached No. 20 on the country chart, shortly before Vassar parted ways with Arista Nashville. Prayer of a Common Man In March 2007, Vassar signed to Universal South Records, which became part of Show Dog-Universal Music in December 2009. His first single for the label, "This Is My Life", was released in mid-2007, peaking at No. 35 on the country music charts. Succeeding it was "Love Is a Beautiful Thing" This song was co-written by Jeffrey Steele and Craig Wiseman, and was previously recorded in 1999 by Canadian singer Paul Brandt under the title "It's a Beautiful Thing". By April 2008, "Love Is a Beautiful Thing" had reached No. 2 on the country charts, and Vassar's first album for Universal South (Prayer of a Common Man) was released. A third single from this album, "I Would", was issued in July 2008 and peaked at No. 26. It was followed in early 2009 by the album's title track, which became the lowest-peaking single of his career at No. 53. Traveling Circus One week after "Prayer of a Common Man" fell from the chart, Vassar charted his eighteenth single, "Bobbi with an I". Released in April 2009, it was the first single from Vassar's fifth studio
