With songs such as "Maybellene" (1955), "Roll Over Beethoven" (1956), "Rock and Roll Music" (1957) and "Johnny B.

Leaving behind his initial base in the American folk music revival, his six-minute single "Like a Rolling Stone", recorded in 1965, enlarged the range of popular music.

The lyrics were heavily influenced by Symbolist poetry and bid farewell to the titular "Baby Blue." There has been much speculation about the real life identity of "Baby Blue", with possibilites including Joan Baez, David Blue, Paul Clayton, Dylan's folk music audience, and even Dylan himself.

Document 8: Yes I Will: "Yes I Will", also known as "I'll Be True to You", is a song written by Gerry Goffin and Russ Titelman. The song was first recorded in 1964 by British Beat group The Hollies who released it as a single in January 1965 where it peaked at number 9 in the United Kingdom. Two versions of this song were released by the Hollies. An alternate take with prominent acoustic guitars and a different intro was included on the band's 1968 Greatest Hits album in the UK since the original single version was only available as a mono mix, and EMI wanted all tracks in stereo, for which only the alternate take existed. This is often described as an "erroneous" version because it does not reflect what was heard on the single. Other examples of this practice include Stay from 1963 in which the famous guitar solo in the middle-eight was recorded live as the mono mix was being made, meaning the stereo version has a different solo, the one that was previously recorded on the multi-(4) track studio tape. A version of the song titled "I'll Be True to You" was recorded by The Monkees and included on their 1966 self-titled debut album. Australia's Twilights also recorded a version on their eponymous 1966 album.
