Welch was born in Los Angeles, California, into a show business family. Welch's father was movie producer and screenwriter Robert L. Welch, who worked at Paramount Pictures in the 1940s and 1950s, producing films starring Paramount's top box office stars, Bob Hope and Bing Crosby (solo, not as a duo). He also worked as a TV producer, responsible for the 25th Annual Academy Awards TV special in 1953 and The Thin Man TV series in 1958-59. Bob's mother, Templeton Fox, had been a singer and actress who worked with Orson Welles' Mercury Theatre in Chicago, Illinois and appeared on TV and in movies from 1962 to 1979.
The band did well in the studio, but their tours were more problematic. Kirwan developed an alcohol dependency and became alienated from Welch and the McVies. Welch held contradictory attitudes towards Kirwan in the 18 months they were bandmates in Fleetwood Mac: On the one hand, their personal relationship was difficult as Welch felt that Kirwan was playing mind games with the band; and on the other hand, Welch had enormous respect for Kirwan's musicianship. In 1999, Welch stated: "He was a talented, gifted musician, almost equal to Peter Green in his beautiful guitar playing and faultless string bends." In a later interview, Welch said: "Danny wasn't a very lighthearted person, to say the least. He probably shouldn't have been drinking as much as he did, even at his young age. He was always very intense about his work, as I was, but he didn't seem to ever be able to distance himself from it... and laugh about it. Danny was the definition of 'deadly serious'." The end for Kirwan came in August 1972, during an American tour, when he stormed off stage in a violent rage after arguing with Welch. Before a concert on that year's US tour, Kirwan and Welch fought over tuning and Kirwan flew into a rage, smashing his guitar and refusing to go onstage. He reportedly smashed his head bloody on a wall in back of the stage, then moved into the sound booth to watch the show, where the band struggled without him as Welch tried to cover his guitar parts. After the fiasco of a show, he criticized the band. Fleetwood subsequently fired Kirwan, partly on the recommendation of Welch. The artistic direction of Fleetwood Mac essentially was left in the hands of Welch and Christine McVie.
