On this day in music history: July 29, 1973 - Led Zeppelin plays three sold out shows at Madison Square Garden in New York City. Touring in support of their then current album “Houses Of The Holy”, the concerts are filmed for inclusion in the film “The Song Remains The Same” (released in October 1976). Before the last show, box office receipts totaling $203,000 are stolen from the safe deposit box at the Drake Hotel where band are staying. The box office receipts disappear sometime between the time the bands road manager Richard Cole and their attorney place the money in the hotel’s safe. Zeppelin’s personal manager Peter Grant holds a press conference discussing the situation. After a complete investigation, the money is never recovered and no one is ever charged in the theft.
