What I am writing below is a mix of speculation, conjecture and solid history. As Trapalhadas... is an odd record, because it mixes comedy skits with songs. The genres of forró and rock n' roll have courted comedy throughout in the past. In the US, Cheech and Chong, Steve Martin and Eddie Murphy all crossed the comedy / rock barrier. Even the Beatles were a traveling comedy skit / music act for a while. This was after their stint in Hamburg and during their earliest period with Brian Epstein as their manager. The concept seems like an old fashioned extension of radio variety shows that mixed comedy and music.
Certain forró acts also did this, like Genival Lacerda, but far longer than the Beatles. Another star called Coronel Ludrú, who was part of the CBS stable of acts in the 60s and 70s, released multiple comedy records (mostly sans-music), apparently marketed for northeastern Brazilian audiences.
As Trapalhadas... from 1970 was an attempt to mix a comedy act with Genival's musical act on record. I am not certain how successful this was as a comedy record. Several of the songs are excellent, though, especially O Bom Daqui Sou Eu. After this point, Genival Lacerda kept the comedy in the songs rather than adding stand-up to his album recordings. Eventually, Lacerda found a successful balance and a permanent musical / comedy marriage with Severina Xique Xique in 1975.
