Saturday afternoon tunes: A big day -- feel the power?

Lots of musical milestones land on this date: In 1896, gold was discovered in the Yukon Territory, which gave Johnny Horton another hit record 64 years later. In 1955, Elvis released his first #1 hit, and Paul Robeson lost his legal appeal against the US State Department's refusal to issue him a passport because he refused to recant some of his pro-Soviet statements. In 1958, Madonna was born. In 1969, it was the last day second day (oops!) of Woodstock.  In 1974, the Ramones played their first gig at CBGB's. And on this date in 1977, Elvis was found dead.
