Through thick and thin, George Harrison and Eric Clapton remained life-long friends. Nothing and no one came between them, not even the woman they both loved, Pattie Boyd. However, Clapton had one grievance against the former Beatle.
Clapton never forgave George for not taking him to meet reggae star, Bob Marley.
Clapton was with The Yardbirds and George with The Beatles when they first met in the early 1960s. In 1977, George told Mitchell Glazer (per George Harrison on George Harrison: Interviews and Encounters) that he didn’t get to know Clapton during their initial meeting. They later met again during a Lovin’ Spoonful concert. George recognized Clapton, but the guitarist looked lonely.
