Consequently, the the group picture for 33-RPM Long Playing album's cover showed a different drummer (Bobot Guerrero), with Tagarro's name stricken off the personnel credits, other than for his mention as composer of one song ("Lady in White Satin").
Bobot Guerrero's entry as the new drummer of Juan Dela Cruz continued through the promotional run of the album and into various concerts and club stints.
Upon the conclusion of the Jesus Christ Superstar production, Edmund Fortuno (aka "Bosyo"), Bing Labrador and Alex Cruz (with guitarist Vic Naldo and bassist Marlon Ilagan) formed a splinter group, Anakbayan which, together with the Manila Symphony Orchestra, performed for another major production run at the Cultural Center, the rock opera, Tommy by The Who.
The versatile Sandy Tagarro returned to the Juan Dela Cruz Band, as lead vocalist and replacing Fortuno as drummer; while Clifford Ho retained the bass chores.
In the wake of this major revamp, the Juan Dela Cruz Band recorded its first album in 1971, entitled Up in Arms, which was released by the Vicor Music Corporation under its Sunshine Records imprint.
However, complications caused Sandy Tagarro to leave abruptly barely after concluding the Up In Arms recording sessions; not even to pose for the album photography.
Music historian Julian Cope narrates in his book, Japrocksampler (Bloomsberry, 2007), that Shinki Chen had recruited Joey Smith (and later, Mike Hanopol) from a Filipino rock group called Zero History, which he found performing in Tokyo's mall district.
(Source: Pinoy Classic Rock.com) They performed that year at the Antipolo Rock Festival (patterned after the legendary Woodstock Rock Festival of 1969) and was subsequently tapped as the featured rock band in tandem with the Manila Symphony Orchestra (conducted by Redentor Romero) for the Philippine production of the rock opera by Tim Rice and Andrew Lloyd Webber, Jesus Christ Superstar, at the Cultural Center of the Philippines.
Consequent to his dramatic part as the Judas character in the rock opera production, Sandy Tagarro vacated his instrumentalist role in the group and was replaced by Clifford Ho as bass guitarist.
