At a very young age Bill McCubbin found himself in Las Vegas working for the multi-talented Bobby Darin. As part of Bobby's band Billy traveled with Bobby
working all over the country and in Vegas and also on Bobby's 1973 NBC The Bobby Darin Show. Bobby introduces "Billy Mac"
during the amazing Mack Is Back DVD.
When Bobby was too ill to continue performing, Billy and the rest of the band went on to work with Tony Orlando.
Still working to keep Bobby's name and music out there, on October 25, 2013, he sang a "tanfastic" version of "Clementine" at The Bootlegger
Bistro in Las Vegas.
