Is five thousand a record? I jam with a fellow regularly who is in his seventies. He retired, after thirty-five years, as a bar musician. He played in Chicago (Illinois USA). He is a very nice guy, and cna play just about any old country song from the 1930's through the 1970's. He says that he used to know around 5000 songs. He's fun to listen to, because someone can ask him to play an old song, and he'll know who wrote it, who recorded it, who played on it, and what was on the "flip side." Sometime, the prople will only remeber a lyric or two. I will ask him about obscure country songs and singers (like Mollie O'Day), and he'll play all of them.
