In 1977 he directed the Broadway musical "The Act", starring Liza Minnelli. The disappointing reception that "New York, New York" received drove Scorsese into depression. By this stage the director had developed a serious cocaine addiction. However, he did find the creative drive to make the highly regarded "The Last Waltz", documenting the final concert by The Band. It was held at the Winterland Ballroom in San Francisco on American Thanksgiving Day, November 25, 1976, and featured one of the most extensive lineups of prominent guest performers at a single concert, including Bob Dylan, Neil Young, Ringo Starr, Muddy Waters, Joni Mitchell, Van Morrison, Paul Butterfield, Neil Diamond, Ronnie Wood, and Eric Clapton. However, Scorsese's commitments to other projects delayed the release of the film until 1978. Another Scorsese-directed documentary, titled "", also appeared in 1978, focusing on Steven Prince, the cocky gun salesman who appeared in "Taxi Driver". A period of wild partying followed, damaging the director's already fragile health. Scorsese helped provide footage for the documentary "Elvis on Tour".
