LISBON, Portugal — Eurovision Song Contest winner Salvador Sobral has given fans a performance of sorts for the first time since his heart transplant.

A video clip of the 28-year-old Portuguese singer covering part of Fleetwood Mac’s “Landslide” was posted on his Facebook page Tuesday.

It’s not clear when or where Sobral made the solo recording that shows him picking out piano chords and singing in English. His representatives didn’t reply to inquiries.

Sobral sang a solo ballad in last year’s Eurovision contest to give Portugal its first win in 53 years of competing. His victory means Portugal will host this year’s Eurovision Song Contest in May.

Sobral has said he hopes to perform live in May.

A Lisbon hospital said this month Sobral made a “very satisfactory” recovery from the transplant he underwent in December.
