"(They Long To Be) Close To You" is more closely associated with the Carpenters, who scored a mammoth hit with it. However, believe it or else, it turned up as an album track on the lone album of Josie & the Pussycats, produced by Danny Janssen's La-La Productions for Capitol in 1970. I'm not entirely sure if it's Patrice Holloway (singing voice for Valerie) or Cherie Moor (Cheryl Ladd, Melody's singing voice) doing the honors here, but give a listen.
8 years later, while on Charlie's Angels, Cheryl Ladd went back into the studio and cut her first solo record. Considering her country music roots, I'd say she might've gone for the crossover audience, but we'll never know, as other than the obligatory special, not much came out of it. Holloway was the only other one who went solo, both before and after being a part of the band.
