"I'll Wait and Pray" is a jazz composition written by Jerry Valentine and George Treadwell. The tune was first recorded on December 5, 1944, by Billy Eckstine and His Orchestra featuring a vocal by Sarah Vaughan, with the recording released in November 1945. Originally conceived as a vocal number, the piece found a second life as an instrumental vehicle for jazz improvisation, with its chord changes proving well suited to bebop and post-bop exploration. Valentine was an arranger and trombonist associated with the Eckstine orchestra during its groundbreaking mid-1940s period, while Treadwell was a trumpeter and manager closely connected to the early bebop scene. Though not among the most frequently called tunes in the standard jazz repertoire, "I'll Wait and Pray" has attracted a steady stream of instrumentalists across several decades. Notable recordings include versions by John Coltrane, Art Blakey and the Jazz Messengers, pianist Benny Green, guitarist Ed Bickert, bassist Lonnie Plaxico, and drummer Jimmy Cobb, among others. The tune's enduring appeal lies in its strong harmonic foundation, which provides fertile ground for creative soloing while retaining the melodic warmth of its vocal origins. It remains a deep cut that rewards musicians who seek it out, occupying a respected if somewhat under-the-radar place in the jazz canon.
