"More Than I Can Say" is a song written by Sonny Curtis and Jerry Allison, both former members of Buddy Holly's band the Crickets. They recorded it in 1959 soon after Holly's death and released it in 1960. Their original version hit No. 42 on British Record Retailer Chart in 1960. It has been notably performed by singers Bobby Vee, Leo Sayer, and Sammy Kershaw.

"More Than I Can Say" was the third single from the Crickets' second release, In Style With the Crickets. The song was written by guitarist Sonny Curtis and drummer Jerry Allison around an hour in 1959. The hook was left unfinished at the time, and at the time of recording, the hook was left this way with no vocals, only the "wo-wo yay-yay," which became a memorable part of the song. The single went on to become a minor hit in the UK, entering the Top 40 and peaking at 26. Curtis considers this song to be one of his most prolific, looking back at the success subsequent artists have had performing it.

Vee is an American pop music singer whose prominence in the music industry arose from tragedy. After Holly, Ritchie Valens and The Big Bopper were killed in a plane crash in February 1959, a then-teenaged Vee was one of a group of local musicians recruited to play at the next leg of a scheduled concert in Fargo, North Dakota. In 1961, Vee (whose other hit singles include "Take Good Care of My Baby" and "The Night Has a Thousand Eyes") recorded "More Than I Can Say", and it reached No. 61 on the Billboard Hot 100 chart. It was a bigger hit in the United Kingdom, where the song and its B-side, "Staying In", peaked at No. 4 on the UK Singles Chart. He also reached No. 8 in New Zealand.
