[2] During the summer of 1963, when Larsson was only 15 years old, Töpel invited him to join Alberts Skiffelgrupp, which at the time only consisted of him and Tommy Blom.

[6] After recruiting drummer Freddie Skantze, Larsson signed a contract for an electric guitar, which would become his primary instrument for the remainder of his career in the group.

[11][12] Larsson remained in obscurity on the group's debut single, "Sleep Little Girl", as he did not contribute to it vocally, nor did he write it or its B-side, "Tell Me You're Mine".

[15] The song was a large departure from the group's earlier, softer sound and began a very fruitful and successful collaboration with producer Anders Henriksson.

[15] In mid-1965, Larsson looked to branch out from the group's regular sound, and began experimenting with various keyboard instruments, most notably the electric organ.

[18] However, for the rest of the band's career, Larsson would largely stay out of the spotlight, writing no more A-sides (excluding ones that were credited as group compositions), but did however compose and sing on their albums.

[23] This resulted in them changing their name to Blond and releasing one album, The Lilac Years, which was recorded in March 1969 and features one of Larsson's compositions, "The Girl I Once Had", which he had written together with Adrian Moar and Kathe Green.

[25][26] His work with the band was largely influential, with Lennart Wrigholm writing that he and Töpel were the best "radar pair guitarists" in Sweden.

[26] Bexér studied at the Stockholm School of Economics in Gothenburg during the 1970s and later became a businessman, opening several businesses involving the production of clothes.
