Every work he sang, composed for other singers, or wrote for instruments, with each kind of date kept apart: recording, disc issue, film premiere, first performance or broadcast, and LP release. Each row is placed at the earliest known point the work existed: composition, first performance or broadcast, film premiere, recording, or original disc. Reissue and anthology years never count as a first appearance; when they are the only dated evidence, the row reads "by" that year. Many works are dated only by the year given in two reference lists: Isis Fathallah's database of his works (Cairo Opera House, 1995) and the chronological list hosted by S. Mneimneh, which appears to derive from it. Both give the year a work first appeared but not whether that was its composition, performance, recording or film, and rows dated this way say so. Select a row to hear it in the player; press Details to see every date, the conflicts between sources, and the links behind them. The ↑ and ↓ keys move through the list.
