The good ol’ days.

Ashley Tisdale reunites with High School Musical co-star Lucas Grabeel for a duet of “What I’ve Been Looking For.”

I’m not going to apologize for marking my calendar every week waiting for a new performance from Ashely Tisdale as part of her Music Sessions on YouTube.

This year she’s cranked out some big ones, including a cover of Elle King’s “Ex’s & Oh’s” with bestie Vanessa Hudgens, Britney Spears’ “Toxic”, Julia Michaels’ debut single “Issues” and a cover of The Chainsmokers and Daya’s Grammy Award winning song, “Don’t Let Me Down.”

Her latest is a nostalgic throwback to her High School Musical days – she invited Grabeel to relive a moment they shared together in the first film where they sing “What I’ve Been Looking For,” but re-worked as a tender piano ballad. The last time they sang this together was a decade ago.
