"Tanya" was composed by Donald Byrd and interpreted by Dexter Gordon (tenor sax) Donald Byrd (trumpet) Art Taylor (drums) NielsHenning Orsted Pedersen (bass), Kenny Drew (piano).

Producer and jazz critic Doug Payne wrote of this piece:
"This remarkable (recording), thankfully captured at Rudy Van Gelder's Englewood Cliffs, New Jersey, studio on June 2, 1964, during one of tenor sax great Dexter Gordon's 'flights' back to the United States, is among one of the great milestones of early sixties jazz."

According to www.jazzdisco.org and others who have commented on this post "Tanya" was recorded at Barclay Studios, Paris, France, June 2, 1964.

I believe "Tanya" was recorded in Paris on June 2nd, 1964 and remastered at Rudy Van Gelder's NJ studio in 1999.
