Hi, Joe. Frankie sings 100% of the show Live. However, Frankie gets support from his backup singers when higher notes are required. The capabilities of Frankie on that stage at 90-years-old are beyond amazing. Frankie Valli is such a legendary act.
@@joewhitehead3Frankie Valli and the Band are so remarkably consistent as to making a sound closest to the studio version as possible. This comes with a lot of experience (which Frankie has). Examples of these skills include breath control, tempo, lyricality. Due to Frankie's skill and talent, his in-studio and Live artistry are very similar which makes some believe he is utilizing other technology (such as lip-syncing or Live autotune).
