Who sang lead vocals on the Eagles' song "I Can't Tell You Why"?

Timothy B. Schmit sang lead vocals on the Eagles’ song “I Can’t Tell You Why.”

The song appeared on The Long Run, the Eagles’ sixth studio album, and marked Schmit’s first Eagles recording with him as lead vocalist. He had joined the band in 1977, replacing Randy Meisner on bass and backing vocals after previously replacing Meisner in Poco.

Schmit began the song and then completed it with Glenn Frey and Don Henley. The trio shared songwriting credit, but Schmit’s distinctive, soulful vocal is the center of the finished track. Frey and Henley added supporting and counterpoint vocals, while Schmit also played bass.

Recorded in March 1978 and released as a single in 1980, the song became a major hit, reaching No. 8 on the Billboard Hot 100. Listeners sometimes confuse the vocal credit because the recording features prominent parts from several Eagles, including Frey’s guitar work and Henley’s backing vocals.
