Perhaps, Eric and Ernie’s finest moment.
Previn is initially enthusiastic as a guest, but he is perplexed by the news that he will not, after all, be conducting Yehudi Menuhin in Mendelssohn‘s Violin Concerto, but Edvard Grieg‘s A minor Piano Concerto with Eric as piano soloist:
Previn: Goodnight, gentlemen.
Ernie: No, no! Please don’t go, Mr Preview!
Ernie: I can assure you that Eric is more than capable.
Previn: Well—all right. I’ll go and get my baton.
Ernie: Please do that.
Previn: It’s in Chicago.
At this point in the sketch Morecambe punches the air with his fist and ad-libs the line “Pow! He’s in! I like him! I like him!”.The television executive Michael Grade has observed that it was Previn’s expert delivery of his lines that caused Morecambe to visibly relax: “Eric’s face lights up as if to say, ‘Oh, yes! This is going to be great!”
