During their 50th-anniversary reunion tour, in 2012, the group played along to a pre-recorded vocal track taken from Carl's 1980 performance of the song at Knebworth. Mike Love said of Carl in a contemporary report, "Nobody ever could or will sing ‘God Only Knows’ as beautifully as he did. It's miserable that he's not there with us. Carl was the real stickler for making the band sound as absolutely perfect as could be. That influence is still felt to this day." The original performance was released on the 2002 live album "".
