In 1967, he recorded a pop song "Let the Heartaches Begin" that went to number one in Britain, followed by a 1968 top 20 hit titled "Mexico", which was the theme of the UK Olympic team that year. "Let the Heartaches Begin" made the lower reaches of the "Billboard" Hot 100 in the US. Baldry was still touring, doing gigs with Bluesology, but the band refused to back his rendition of "Let the Heartaches Begin", and left the stage while he performed to a backing-tape played on a large Revox tape-recorder.
