Lee Seung-chul's vocal ability is a case of resurrection after surgery in his 50s

‌In his 40s, he couldn't hit high notes, so he would get by with falsetto, and most concert reviews said his live performances weren't as good as expected.
There was even a period when he was mocked, with people saying he sang worse than actor Yoon Sang-hyun, who remade "Never Ending Story."
Of course, he wasn't actually bad, but there was a lot of talk about him being a singer with extreme inconsistency and poor self-management.
However, after undergoing vocal cord surgery around 2018 in his 50s, his voice recovered to a degree that even surprised him.
Even though he is now in his 60s, he belts out high-note ad-libs that he wouldn't have even attempted before.
