Jeremy sings three songs during his guest appearance on the TV variety show featuring model, actress and all-around 1960s icon, Twiggy.

The first is "She Moves Through the Fair," a haunting and widely recorded tune based on a traditional Irish folk song. --  Wikipedia info 

The second is a rendition of "Love Unspoken," which Jeremy performed in  The Merry Widow. Jeremy cuts a striking figure while crooning and waltzing with Twiggy. 

The pair wrap up the show with a cute duet of "Two Sleepy People," a song written by Frank Loesser and Hoagy Carmichael and used in the 1938 movie, Thanks For The Memory. ( Lyrics here)
