As far as it's known, Bruce performed the song 2 times with the Castiles:
1965-10-00 Reception Hall, Monmouth County, NJ
One show, with The Castiles the sole act on the bill. The 27 song titles of this show plus two titles that are illegible have been culled from a surviving inventory/setlist document that was originally in the possession of a member of The Castiles. This list is believed to have emanated from a wedding reception the band performed in the autumn of 1965. With the exception of "Sidewalk" (co-written by Bruce) all of the songs are covers of other artist’s material, with the most recently released song at the time being Sonny & Cher’s "I Got You Babe" (July 1965). The setlist includes numerous 1964-1965 'British Invasion" hits by the Stones, Yardbirds, Kinks, Zombies and Beatles - a clear indication of the kind of music the band was playing at teen gigs. The high proportion of 1950s ballad material in this particular show (sung by George Theiss, not Bruce) is likely the result of it being a wedding, with manager Tex Vinyard making sure his boys also catered to the older relatives in attendance. These include the G-Clefs’ "I Understand", Acker Bilk’s "Stranger On The Shore", Don & Juan’s "What’s Your Name" and Anton Karas’ "The Third Man Theme". There is no circulating audio of any of this performance . Frank Marziotti has recalled the bride's choice of song was the jazz standard "Moonglow".
1965-08-00 Woodhaven Swim Club, Freehold, NJ
One evening show, featuring the The Castiles in their first-ever verified public performance. Although the exact date is uncertain it is believed this took place in mid-August. The Woodhaven Swim Club was located on East Freehold Road - it later became the home of the local YMCA. According to 1970s comments by Castiles manager Tex Vinyard the group received a whopping total of $35 for the show. The show closed with a rock arrangement of "In The Mood".
