From the wiki: “‘I Just Can’t Help Believing’ is a song written by Barry Mann and Cynthia Weil. The song was most successful after it was recorded by B.J. Thomas and released by him as a single in 1970. It went to #9 on the Billboard Hot 100 singles chart, and spent one week at #1 on the Easy Listening (adult contemporary) chart. The first recording and single release was by the song’s co-writer, Barry Mann, in 1968 (with no apparent chart success), and as album tracks in 1969 by Bobby Vee, and Leonard Nimoy.
“The song was also recorded by Elvis Presley in 1970 for the documentary Elvis: That’s the Way It Is. The film captures Presley’s Summer Festival in Las Vegas at the International Hotel during August 1970. It is considered one of Elvis’ best live performances as both orchestra and vocals are virtually flawless (even if he does start the performance reading from a lyric sheet). That’s the Way It Is was Presley’s first non-dramatic film since the beginning of his film career in 1956, giving a clear view of Presley’s return to live performances after years of making films. His performance in the film of ‘I Just Can’t Help Believing’ was released as a single in the UK in November 1971, peaking at #6.”
