The passing of "Glee" star Cory Monteith left a giant hole in a cast of superstars -- a cast who can sing just as well as they can act on the hit FOX show.

The 31-year-old made a memorable first impression when he made his singing debut performing REO Speedwagon's "I Can't Fight This Feeling Anymore" in the shower in the pilot.

And from then, his duets with on and off-screen love interest Lea Michele continued to impress anyone who watched on a weekly basis.

In an tragic turn of events, the last song he was seen performing on the show would also be one Cory sang during the first episode -- a song that would become the show's most popular cover, Journey's "Don't Stop Believing."
