Oscars 2015: Watch Jennifer Hudson Sing 'In Memoriam' Song on 'Smash'
"I Can't Let Go" is an original song written for season 2 of the NBC musical TV series. In the show, the song was written for the musical Hit List by characters Jimmy Collins (Jeremy Jordan) and Kyle Bishop (Andy Mientus) for Broadway superstar Veronica Moore -- played by none other than Jennifer Hudson.
The lyrics are fitting for a "gone too soon" tribute: "If I hang on to this heartache/ Then my soul will not be free/ So I keep trying, but I just cannot let go."
