Elvis Presley’s Can’t Help Falling in Love peaked at number two on the pop
chart and went to number one on the Easy Listening chart for six weeks. The
song was featured in Elvis Presley‘s 1961 film, Blue Hawaii.

The instrumental section of the song was recorded at United Western Recorders, Hollywood, California, with the session engineered by Chuck Britz and produced
by Brian Wilson. The session took 20 takes to achieve the master take of the
song. The recording included Carl on twelve string guitar among other session
musicians collectively known as The Wrecking Crew. A strip of masking tape was
placed over the strings of a piano  while the bottoms of two plastic orange juice
bottles were used for percussion. The final vocal track of “God Only Knows” was completed on April 11, 1966. The song was voted 25 in Rolling Stone magazine’s
500 Greatest Songs of All Time.

"It Doesn’t Matter Anymore" was written by Paul Anka and recorded
by Buddy Holly in 1958. The song reached No. 13 as a posthumous
hit on the Billboard Hot 100 charts in early 1959 shortly after Holly
was killed in a plane crash on February 3, 1959. The single was a
two-sided hit, backed with "Raining in My Heart".
